	* editline.3, el.c, el.h, histedit.h, terminal.c, vi.c: [Prereq for
	  PR bin/58609] Add EL_GETENV to libedit

	  When interacting with the shell, and perhaps other applications,
	  editline needs to obtain the values of some environment
	  variables.

	  Normally getenv(3) does that - but that doesn't work when being
	  used in sh(1) as getenv() simply accesses the environment as it
	  was when sh(1) was invoked - after that, in sh anyway, that
	  environment is simply abandoned (well, kind of) - but certainly
	  no changes made by the shell will be reflected there.

	  To allow editline to obtain current values of environment
	  variables, add a new el_set()/el_get() "op" parameter value,
	  which can be used to instruct editline which function to use for
	  the purpose.	 That is EL_GETENV.

	  This is part of a (long pending, awaiting testing) fix for PR
	  bin/58609 - but I'm getting tired of having it sitting
	  uncommitted in my source tree - and I think this part is self
	  contained, and simple enough, to simply commit.

	* history.c: Don't fchmod(fileno(fp), ...) in history_save_fp().

	  There are two reasons for this, first, the permissions of the
	  history file should be able to be set by the user, not forced to
	  0600 every time the history file is overwritten (or appended to).

	  And more importantly, the fp used for fileno(fp) might have come
	  from fmemopen() or funopen() (etc) - none of which put a file
	  descriptor in the "fd" field (ie: fileno(fp) == -1).

	  To compensate for that, when a history file is opened (in
	  history_save()) set the default permissions then - if the file is
	  actually created.  As fopen() cannot do that (it simply uses
	  0666&~umask) create the (normal type) of fp using (approximately)
	  fdopen(open(...), ...) where the open supplies the 0600 default
	  permissions that are desired here (which might still be
	  restricted even more by the umask).	Callers using
	  history(...,H_SAVE_FP,...) or history(...,H_NSAVE_FP,...) now
	  need to look after any permission setting required themselves
	  (but as the doc says absolutely nothing about that, one way or
	  the other, what happens in this area has always been unspecified,
	  and still is)

	  One "feature" of the fchmod() method is lost here - apart from
	  forcing the 0600 permissions (which isn't really desirable) that
	  fchmod() would also have failed if the current (effective) uid is
	  not the owner of the history file (or root).	  If that is
	  required, a test for it could be added later - the effect would
	  be as it has always been, the file named must have been writable
	  (or its directory writable if the file did not exist) the open
	  would occur (potentially truncating the file) after which the
	  fchmod() would be attempted, possibly failing, and if so, never
	  writing anything.   Any new uid test would work the same way.

	  OK christos@

	  before the filename to be expanded, as in

	  Before this change, the above would not expand any possible
	  completions, even if they existed, because it would choose to
	  look for files whose names started with " bar".

	  Quoting of special characters in filename completion was

	  matches as well. For example:

	  $ touch 'foo bar' $ touch 'foo baz' $ ls fo<TAB> autocompletes to
	  => $ ls foo\ ba hitting <TAB> again shows: foo bar foo baz

	  This required unescaping escape sequences generated during last

	  While there, also update the test to include cases for multiple

2016-10-31 18:46  abhinav

	* filecomplete.c: Fix file name auto completion in one specific
	  case.

	  For example if you do $mkdir -p /tmp/dir1/dir2

	  Then: $ls /tmp/di <TAB> auto completes to $ls /tmp/dir1/

	  Hitting <TAB> again auto completes to $ls /tmp/dir1/dir2

	  Whereas it should auto complete to $ls /tmp/dir1/dir2/

	  Essentially, in cases like above where you have to hit <TAB>
	  twice to get to the match and there is only one match (because
	  only one file/sub-directory) then auto complete doesn't work
	  correctly. It doesn't append a trailing slash (in case of
	  directory) or a space (in case of a file) to the match name.

	  I have tested file name completion in sh(1) and symbol completion
	  in gdb after this change.

	* readline.c: Fix previous to better match readline behavior (Ingo
	  Schwarze)

2016-06-02 17:11  christos

	* readline.c: From Ingo Schwarze:

	  In libedit, the only way how H_ENTER can fail is memory
	  exhaustion, too, and of course it is handled gracefully,
	  returning -1 from history().	So of course, we will continue to
	  handle it gracefully in add_history() as well, but we are free to
	  decide what to do with the library state in this case because GNU
	  just dies...

	  I think the most reasonable course of action is to simply not
	  change the library state in any way when add_history() fails due
	  to memory exhaustion, but just return.

	  If H_ENTER does not fail, we know that the history now contains
	  at least one entry, so there is no need any longer to check the
	  H_GETSIZE return value.  And we can of course always set
	  current_history_valid.

	  While testing these changes, i noticed three problems so closely
	  related that i'd like to fix them in the same diff.

	   1. libedit has the wrong prototype for add_history().
	      GNU readline-6.3 defines it as void add_history(const char
	  *).
	      Of course, that is very stupid - no way to report problems to
	      the caller!  But the whole point of a compatibility mode is
	      being compatible, so we should ultimately change this.
	      Of course, changing the prototype of a public symbol requires
	      a libedit major bump.  I don't want to do that casually.
	      Rather, i will take a note and change the prototype the next
	      time we need a libedit major bump for more important reasons.
	      For now, let's just always return 0.

	   2. While *implicitely* pushing an old entry off the history
	      increments history_base in GNU readline, testing reveals that
	      *explicitly* deleting one does not.  Again, this is not
	      documented, but it applies to both remove_history() and
	      stifle_history().  So delete history_base manipulation
	      from stifle_history(), which also allows to simplify the
	      code and delete two automatic variables.

	   3. GNU readline add_history(NULL) crashes with a segfault.
	      There is nothing wrong with having a public interface
	      behave that way.	Many standard interfaces do, including
	      strlen(3).  Such crashes can even be useful to catch
	      buggy application programs.
	      In libedit/readline.c rev. 1.104, Christos made add_history()
	      silently ignore this coding error, according to the commit
	      message to hide a bug in nslookup(1).  That change was never
	      merged to OpenBSD.  I strongly disagree with this change.
	      If nslookup(1) is still broken, that program needs to be
	      fixed instead.  In any case, delete the bogus check; hiding
	      bugs is dangerous.

	* el.h, keymacro.c, read.c: From Ingo Schwarze:

	  Reduce obfuscation of errno handling. There is only one purpose
	  non-local errno handling is needed for:  Inside el_wgets(),
	  several functions call down indirectly to el_wgetc(), many of
	  them via the dispatch table.	When el_wgetc() fails, it does
	  properly report failure, but then various cleanup is done which
	  may clobber errno.  But when returning due to failure, el_wgets()
	  wants to have errno set to the reason of the original read
	  failure, not to the reason of some subsequent failure of some
	  cleanup operation.  So el_wgetc() needs to save errno, and if
	  it's non-zero, el_wgets() needs to restore it on failure.

	  This core logic is currently obscured by the fact that el_errno
	  is set and inspected at some additional places where it isn't
	  needed.  Besides, since el_wgetc() and and el_wgets() are both in
	  read.c, el_errno does not need to be in struct editline, it can
	  and should be local to read.c in struct el_read_t.

	  Let's look at what can be simplified.

	   1. keymacro_get() abuses el_errno instead of having a proper
	      error return code.  Adding that error return code is easy
	      because node_trav() already detects the condition and an
	      adequate code is already defined.  Returning it, testing
	      for it in read_getcmd(), and returning with error from there
	      removes the need to inspect el_errno from el_wgets() after
	      calling read_getcmd().
	      Note that resetting lastchar and cursor and clearing
	  buffer[0]
	      is irrelevant.  The code returns from el_wgets() right
	  afterwards.
	      Outside el_wgets(), these variables are no longer relevant.
	      When el_wgets() is called the next time, it will call
	  ch_reset()
	      anyway, resetting the two pointers.  And as long as lastchar
	      points to the beginning of the buffer, the contents of the
	      buffer won't be used for anything.

	   2. read_getcmd() doesn't need to set el_errno again after
	  el_wgetc()
	      failure since el_wgetc() already did so.	While here, remove
	      the silly "if EOF or error" comments from the el_wgetc()
	      return value tests.  It's a public interface documented in a
	      manual, so people working on the implementation can obviously
	      be expected to know how it works.  It's a case of

		count++;  /* Increment count. */

	   3. In the two code paths of el_wgets() that lead up to "goto
	  noedit",
	      there is no need to save the errno because nothing that might
	      change it happens before returning.

	  For clarity, since el_wgets() is the function restoring the
	  errno, also move initializing it to the same function.

	  Finally, note that restoring errno when the saved value is zero
	  is wrong.  No library code is ever allowed to clear a previously
	  set value of errno.  Only application programs are allowed to do
	  that, and even they usually don't need to do so, except when
	  using certain ill-designed interfaces like strtol(3).

	  I tested that the behaviour remains sane in the following cases,
	  all during execution of el_wgets(3) and with a signal handler for
	  USR1 installed without SA_RESTART.

	   * Enter some text and maybe move around a bit.
	     Then send a USR1 signal.
	     The signal gets processed, then read_char() resumes reading.
	     Send another USR1 signal.
	     Now el_wgets() sets errno=EINTR and returns -1.

	   * Press Ctrl-V to activate ed-quoted-insert.
	     Then send a USR1 signal.
	     The signal gets processed, then read_char() resumes reading.
	     Send another USR1 signal.
	     ed_quoted_insert() returns ed_end_of_file(), i.e. CC_EOF,
	     and el_wgets() returns 0.

	   * Press a key starting a keyboard macro.
	     Then send a USR1 signal.
	     The signal gets processed, then read_char() resumes reading.
	     Send another USR1 signal.
	     Now el_wgets() sets errno=EINTR and returns -1.

	   * Press : to enter builtin command mode.
	     Start typing a command.
	     Then send a USR1 signal.
	     The signal gets processed, then read_char() resumes reading.
	     Send another USR1 signal.
	     Now c_gets() returns -1, ed_command() beeps and returns
	  CC_REFRESH,
	     and el_wgets() resumes operation as it should.

	  I also tested with "el_set(el, EL_EDITMODE, 0)", and it returns
	  the right value and sets errno correctly.

	* editline.3, editrc.5: documentation improvements (Ingo Schwarze)

2016-05-22 21:44  christos

	* chared.c, chared.h, common.c, el.c, read.c, read.h: Stop the read
	  module from poking the el_chared.c_macro data structure currently
	  belonging to the chared module.  The read module does so from
	  three of its functions, while no other module uses the macro
	  data, not even the chared module itself.  That's quite logical
	  because macros are a feature of input handling, all of which is
	  done by the read module, and none by the chared module.  So move
	  the data into the read modules's own opaque data structure,
	  struct el_read_t.

	  That simplifies internal interfaces in several respects: The
	  semi-public chared.h has one fewer struct, one fewer #define, and
	  one fewer member in struct el_chared_t; all three move to one
	  single C file, read.c, and are now module-local.  And the
	  internal interface function ch_reset() needs one fewer argument,
	  making the code of many functions in various modules more
	  readable.

	  The price is one additional internal interface function,
	  read_end(), 10 lines long including comments, called publicly
	  from exactly one place: el_end() in el.c.  That's hardly an
	  increase in complexity since most other modules already have
	  their *_end() function, read.c was the odd one out not having
	  one.

	* readline.c: From Bastian Maerkisch, via Igno Schwarze:

	  Even though section "2.3.3 Information About the History List" of
	  the history(3) info(1) manual only says

	    -- Function: int where_history (void)
	       Returns the offset of the current history element.

	  which maybe isn't completely clear, a plausible implementation is
	  that the offset returned is the same offset that can be used for
	  history_set_pos(), i.e. that it is 0 for the oldest entry and
	  increases with time, and that's how the GNU implementation
	  behaves indeed.

	  The libedit implementation, on the other hand, returns 1 for the
	  newest entry and increases going back in time.

2016-05-09 23:27  christos

	* editline.3, editline.7, readline.c: GNU readline(3) regards
	  history chronologically, that is, from the perspective of the
	  dawn of time, so "next" means "newer" and "previous" means
	  "older".  Libedit, by contrast, uses reverse chronology and
	  regards history from the perspective of the present, such that
	  "next" means "longer ago" and "previous" means "not so long ago".

	  The following patch fixes previous_history() and next_history()
	  as proposed by Bastian Maerkisch.

	  But there is a related problem demonstrated by Bastian's
	  regression tests that his patch did not fix:	next_history() can
	  advance not only to the newest entry, but beyond it, which core
	  libedit cannot do.  So that feature must be implemented locally
	  in readline.c.

	  With that, the last of Bastians tests is fixed,
	  test_movement_direction().

	  This patch also improves libedit documentation to more clearly
	  state what "previous" and "next" mean.  GNU readline
	  documentation is just as unclear, but we can't easily fix that
	  since libedit doesn't include its own readline.3 manual.

	  (Ingo Schwarze)

2016-05-09 23:25  christos

	* readline.c: The libedit implementation of history_get() also
	  differs from the GNU implementation:	libedit goes to the entry
	  with the given number stored in the HistEvent structure, while
	  GNU subtracts history_base, then advances that many entries from
	  the oldest one.  If entries were removed in between, GNU advances
	  further than libedit.

	  The call sequence H_CURR, H_DELDATA, H_CURR, H_NEXT_EVDATA looks
	  weird, as if part of that must somehow be redundant.	But
	  actually, the user interface is so counter-intuitive that every
	  single step is really required.

	   - The first H_CURR is needed to be able to go back after an
	  error.
	   - The H_DELDATA is needed to move the cursor.  Even though it
	  takes
	     a pointer to ev, that structure is not filled in when the call
	     succeeds.	H_DELDATA only moves the cursor, it doesn't tell us
	     the new event number.
	   - Consequently, the second H_CURR is required to get ev.num
	  filled
	     in.  But it doesn't return the data because ev has no field
	  for
	     that.
	   - So even though the cursor is already positioned correctly,
	     H_NEXT_EVDATA is needed as the final step merely to get the
	  data.

	* chared.c: A very simple, non-intrusive patch to fix a segfault
	  (and a functional error) in c_gets(), file chared.c.

	  Run any program using libedit in the default way.  At the
	  el_[w]gets() prompt, invoke ed-command (for example, in emacs
	  mode, press the escape key, then type the letter 'x').  You
	  should see a ": " prompt.  Type the letter 'x' again.  Now press
	  the backspace key a few times, looking at the screen after each
	  key press:

	   - The 1st BS deletes the 'x'.
	   - The 2nd BS deletes the blank after the prompt.
	   - The 3rd BS deletes the colon of the prompt.
	   - The 4th BS moves the cursor up one line.
	   - The 5th BS gives me "Segmentation fault (core dumped)".

	  Depending on your platform, it might take a few more or a few
	  less backspaces for the buffer underrun to trigger the segfault,
	  but you should be able to hit it sooner or later no matter what.

	  Run the same program again, connect again and invoke ed-command
	  again.  Now type: 'b', backspace, 'i', backspace, 'n', backspace,
	  'd', enter.  The "bind" command gets executed, even though you
	  deleted what you typed before hitting enter.

	* chartype.h, eln.c: From Ingo Schwarze:

	  el_getc() for the WIDECHAR case, that is, the version in eln.c.
	  For a UTF-8 locale, it is broken in four ways:

	   1. If the character read is outside the ASCII range, the
	  function
	      does an undefined cast from wchar_t to char.  Even if wchar_t
	      is internally represented as UCS-4, that is wrong and
	  dangerous
	      because characters beyond codepoint U+0255 get their high
	  bits
	      truncated, meaning that perfectly valid printable Unicode
	      characters get mapped to arbitrary bytes, even the ASCII
	  escape
	      character for some Unicode characters.  But wchar_t need not
	      be implemented in terms of UCS-4, so the outcome of this
	  function
	      is undefined for any and all input.

	   2. If insufficient space is available for the result, the
	  function
	      fails to detect failure and returns garbage rather than -1 as
	      specified in the documentation.

	   3. The documentation says that errno will be set on failure, but
	      that doesn't happen either in the above case.

	   4. Even for ASCII characters, the results may be wrong if
	  wchar_t
	      is not using UCS-4.

	  makelist, map.c, parse.c, refresh.c, refresh.h, search.c,
	  search.h, terminal.c, terminal.h, tty.c, vi.c: From Ingo
	  Schwarze:

	  As we have seen before, "histedit.h" can never get rid of
	  including the <wchar.h> header because using the data types
	  defined there is deeply ingrained in the public interfaces of
	  libedit.

	  Now POSIX unconditionally requires that <wchar.h> defines the
	  type wint_t.	Consequently, it can be used unconditionally, no
	  matter whether WIDECHAR is active or not.  Consequently, the
	  #define Int is pointless.

	  Note that removing it is not gratuitious churn.  Auditing for
	  integer signedness problems is already hard when only fundamental
	  types like "int" and "unsigned" are involved.  It gets very hard
	  when types come into the picture that have platform-dependent
	  signedness, like "char" and "wint_t".  Adding yet another layer
	  on top, changing both the signedness and the width in a platform-
	  dependent way, makes auditing yet harder, which IMHO is really
	  dangerous.  Note that while removing the #define, i already found
	  one bug caused by this excessive complication - in the function
	  re_putc() in refresh.c.  If WIDECHAR was defined, it printed an
	  Int = wint_t value with %c.  Fortunately, that bug only affects
	  debugging, not production.  The fix is contained in the patch.

	  With WIDECHAR, this doesn't change anything.	For the case
	  without WIDECHAR, i checked that none of the places wants to
	  store values that might not fit in wint_t.

	  This only changes internal interfaces; public ones remain
	  unchanged.

	* chartype.c, chartype.h, read.c: From Ingo Schwartze:

	  Next step:  Remove #ifdef'ing in read_char(), in the same style
	  as we did for setlocale(3) in el.c.

	  A few remarks are required to explain the choices made.

	   * On first sight, handling mbrtowc(3) seems a bit less trivial
	     than handling setlocale(3) because its prototype uses the data
	     type mbstate_t from <wchar.h>.  However, it turns out that
	     "histedit.h" already includes <wchar.h> unconditionally (i
	  don't
	     like headers including other headers, but that ship has
	  sailed,
	     people are by now certainly used to the fact that including
	     "histedit.h" doesn't require including <wchar.h> before), and
	     "histedit.h" is of course included all over the place.  So
	  from
	     that perspective, there is no problem with using mbrtowc(3)
	     unconditionally ever for !WIDECHAR.

	   * However, <wchar.h> also defines the mbrtowc(3) prototype,
	     so we cannot just #define mbrtowc away, or including the
	  header
	     will break.  It would also be a bad idea to porovide a local
	     implementation of mbrtowc() and hope that it overrides the one
	     in libc.  Besides, the required prototype is subtly different:
	     While mbrtowc(3) takes "wchar_t *" as its first argument, we
	     need a function that takes "Char *".  So unfortunately, we
	  have
	     to keep a ct_mbrtowc #define, at least until we can maybe get
	     rid of "Char *" in the more remote future.

	   * After getting rid of the #else clause in read_char(), we can
	     pull "return 1;" into the default: clause.  After that, we can
	     get rid of the ugly "goto again_lastbyte;" and just "break;".
	     As a bonus, that also gets rid of the ugly CONSTCOND.

	   * While here, delete the unused ct_mbtowc() from chartype.h.

	  Schwarze)

2016-02-12 16:11  christos

	* read.c: From Ingo Schwarze:

	  If CHARSET_IS_UTF8 is not set, read_char() is broken in a large
	  number of ways:

	   1. The isascii(3) check can yield false positives.  If a string
	  in
	      an arbitrary encoding contains a byte in the range 0..127,
	      that does not at all imply that it forms a character all by
	      itself, and even less that it represents the same character
	      as in ASCII.  Consequently, read_char() may return characters
	      the user never typed.
	      Even if the encoding is not state dependent, the assumption
	  that
	      bytes in the range 0..127 represent ASCII characters is
	  broken.
	      Consider UTF-16, for example.

	   2. The reverse problem can also occur.  In an arbitrary
	  encoding,
	      there is no guarantee that a character that can be
	  represented
	      by ASCII is represented by a seven-bit byte, and even less by
	      the same byte as in ASCII.
	      Even for single-byte encodings, these assumptions are broken.
	      Consider the ISO 646 national variants, for example.
	      Consequently, the current code is insufficient to keep ASCII
	      characters working even for single-byte encodings.

	   3. The condition "++cbp != 1" can never trigger (because
	  initially,
	      cbp is 0, and the code can only go back up via the final
	  goto,
	      which has another cbp = 0 right before it) and it has no
	  effect
	      (because cbp isn't used afterwards).

	   4. bytes = ct_mbtowc(cp, cbuf, cbp) is broken.  If this returns
	  -1,
	      the code assumes that is can just call mbtowc(3) again for
	  later
	      input bytes.  In some implementations, that may even be
	  broken
	      for state-independent encodings, but trying again after
	  mbtowc(3)
	      failure certainly produces completely erratic and meaningless
	      results in state-dependent encodings.

	   5. The assignment "*cp = (Char)(unsigned char)cbuf[0]" is
	      completely bogus.  Even if the byte cbuf[0] represents a
	      character all by itself, which it usually will not, whether
	      or not the cast produces the desired result depends on the
	      internal representation of wchar_t in the C library, which
	      the application program can know nothing about.  Even for
	  ASCII
	      in the C/POSIX locale, an ASCII character other than '\0' ==
	      L'\0' == 0 need not have the same numeric value as a char and
	      as a wchar_t.

	  To summarize, this code only works if all of the following
	  conditions hold:

	   - The encoding is a single-byte encoding.
	   - ASCII is a subset of the encoding.
	   - The implementation of mbtowc(3) in the C library does not
	     require re-initialization after encoding errors.
	   - The implementation of wchar_t in the C library uses the
	     same numerical values as ASCII.

	  Otherwise, it silently produces wrong results.

	  The simplest way to fix this is to just use the same code as for
	  UTF-8 (right above).	Of course, that causes functional changes
	  but that shouldn't matter since current behaviour is undefined.

	  The patch below provides the following improvements:

	   - It works for all stateless single-byte encodings, no matter
	     whether they are somehow related to ASCII, no matter how
	     mb[r]towc(3) are internally implemented, and no matter how
	     wchar_t is internally represented.
	   - Instead of producing unpredictable and definitely wrong
	     results for non-UTF-8 multibyte characters, it behaves in
	     a well-defined way: It aborts input processing, sets errno,
	     and returns failure.
	     Note that short of providing full support for arbitrary
	  locales,
	     it is impossible to do better.  We cannot know whether a given
	     unsupported locale is state-dependent, and for a
	  state-dependent
	     locale, it makes no sense to retry parsing after an encoding
	     error, so the best we can do is abort processing for *any*
	     unsupported multi-byte character.
	   - Note that single-byte characters in arbitrary
	  state-independent
	     locales still work, even in locales that may potentially also
	     contain multibyte characters, as long as those don't occur in
	     input.  I'm not sure whether any such locales exist in
	  practice...

	  Tested with UTF-8 and C/POSIX on OpenBSD.  Also tested that in
	  the C/POSIX locale, non-ASCII bytes get through unmangled.  You
	  may wish to test with ISO-LATIN on NetBSD if NetBSD supports
	  that.

	  (Ingo Schwarze)

2016-02-08 18:18  christos

	* chartype.h, read.c: UTF-8 fixes from Ingo Schwarze:

	   1. Assume that errno is non-zero when entering read_char()
	      and that read(2) returns 0 (indicating end of file).
	      Then, the code will clear errno before returning.
	      (Obviously, the statement "errno = 0" is almost always
	       a bug unless there is save_errno = errno right before it
	       and the previous value is properly restored later,
	       in all reachable code paths.)

	   2. When encountering an invalid byte sequence, the code discards
	      all following bytes until MB_LEN_MAX overflows; consider, for
	      example, 0xc2 immediately followed by a few valid ASCII
	  bytes.
	      Three of those ASCII bytes will be discarded.

	   3. On a POSIX system, EILSEQ will always be set after reading a
	      valid (yes, valid, not invalid!) UTF-8 character.  The reason
	      is that mbtowc(3) will first be called with a length limit
	      (third argument) of 1, which will fail, return -1, and - on
	      a POSIX system - set errno to EILSEQ.
	      This third bug is mitigated a bit because i couldn't find any
	      system that actually conforms to POSIX in this respect:  None
	      of OpenBSD, NetBSD, FreeBSD, Solaris 11, and glibc set errno
	      when an incomplete character is passed to mbtowc(3), even
	  though
	      that is required by POSIX.
	      Anyway, that mbtowc(3) bug will be fixed at least in OpenBSD
	      after release unlock, so it would be good to fix this bug in
	      libedit before fixing the bug in mbtowc(3).

	  How can these three bugs be fixed?

	   1. As far as i understand it, the intention of the bogus errno =
	  0
	      is to undo the effects of failing system calls in el_wset(),
	      sig_set(), and read__fixio() if the subsequent read(2)
	  indicates
	      end of file.  So, restoring errno has to be moved right after
	      read__fixio().  Of course, neither 0 nor e is the right value
	      to restore: 0 is wrong if errno happened to be set on entry,
	  e
	      would be wrong because if one read(2) fails but a second
	  attempt
	      succeeds after read__fixio(), errno should not be touched.
	  So,
	      the errno to be restored in this case has to be saved before
	      calling read(2) for the first time.

	   2. Solving the second issue requires distinguishing invalid and
	      incomplete characters, but that is impossible with the
	  function
	      mbtowc(3) because it returns -1 in both cases and sets errno
	      to EILSEQ in both cases (once properly implemented).

	      It is vital that each input character is processed right
	  away.
	      It is not acceptable to wait for the next input character
	  before
	      processing the previous one because this is an interactive
	      library, not a batch system.  Consequently, the only
	  situation
	      where it is acceptable to wait for the next byte without
	  first
	      processing the previous one(s) is when the previous one(s)
	  form
	      an incomplete sequence that can be continued to form a valid
	      character.

	      Consequently, short of reimplementing a full UTF-8 state
	  machine
	      by hand, the only correct way forward is to use mbrtowc(3).
	      Even then, care is needed to always have the state object
	      properly initialized before using it, and to not discard a
	  valid
	      ASCII or UTF-8 lead byte if it happens to follow an invalid
	      sequence.

	   3. Fortunately, solution 2. also solves issue 3. as a side
	  effect,
	      by no longer using mbtowc(3) in the first place.

	* Makefile: Add new Makefile knob, USE_FORT, which extends USE_SSP
	  by turning on the FORTIFY_SOURCE feature of libssp, thus checking
	  the size of arguments to various string and memory copy and set
	  functions (as well as a few system calls and other miscellany)
	  where known at function entry.  RedHat has evidently built all
	  "core system packages" with this option for some time.

	  This option should be used at the top of Makefiles (or
	  Makefile.inc where this is used for subdirectories) but after any
	  setting of LIB.

	  This is only useful for userland code, and cannot be used in libc
	  or in any code which includes the libc internals, because it
	  overrides certain libc functions with macros.  Some effort has
	  been made to make USE_FORT=yes work correctly for a full-system
	  build by having the bsd.sys.mk logic disable the feature where it
	  should not be used (libc, libssp iteself, the kernel) but no
	  attempt has been made to build the entire system with USE_FORT
	  and doing so will doubtless expose numerous bugs and misfeatures.

	  Adjust the system build so that all programs and libraries that
	  are setuid, directly handle network data (including serial comm
	  data), perform authentication, or appear likely to have (or have
	  a history of having) data-driven bugs (e.g. file(1)) are built
	  with USE_FORT=yes by default, with the exception of libc, which
	  cannot use USE_FORT and thus uses only USE_SSP by default.
	  Tested on i386 with no ill results; USE_FORT=no per-directory or
	  in a system build will disable if desired.

	* filecomplete.c, filecomplete.h, readline.c: Bug reported from
	  Martin Dietze:

	      The place to change the completion_append_character is
	      usually somewhere in the `rl_completion_entry_function'
	      callback which is where one usually can distinguish between
	      file- or dir-like entries to append a slash for dirs etc.

	      This does no longer work since `fn_complete()' takes the
	      `append_character' as argument before the callback is
	  executed,
	      so that changes to the variable
	  `rl_completion_append_character'
	      have in fact no effect for the current completion.

	  Fix by adding a function that returns the
	  rl_completion_append_character, when it gets passed in a filename
	  in readline emulation.

	  wants the clean semantics    it must specifically append to
	  CLEANFILES.	 Resolves PR toolchain/5204.

	  * To recap: .d (depend) files are generated for all files in SRCS
	  and DPSRCS   that have a suffix of: .c .m .s .S .C .cc .cpp .cxx

	  * If YHEADER is set, automatically add the .y->.h to DPSRCS &
	  CLEANFILES

	  * Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} *.d	depend upon
	  ${DPSRCS}

	  * Deprecate the (short lived) DEPENDSRCS

	  Update the various Makefiles to these new semantics; generally
	  either adding to CLEANFILES (because DPSRCS doesn't do that
	  anymore), or replacing specific .o dependencies with DPSRCS
	  entries.

	  Tested with "make -j 8 distribution" and "make distribution".

	  The posix 'sh' specification defines vi-mode editing quite
	  tightly.  The netbsd libedit code (used by sh to do this) was
	  missing several features, there were also minor errors in others.

	  Compare netbsd sh to the definition available from:
	  http://www.opengroup.org/onlinepubs/007904975/utilities/sh.html
	  In particular the following were not supported:     U - undo all
	  changes to line    | - goto column	     Y - yank to end of
	  line	       y - yank        # - comment out current line    @ -
	  take input from shell alias [1]     G - goto numbered line in
	  history buffer	v - edit history line with vi	_ - append
	  word from last input line    . - redo last command Other minor
	  changes have also been made.

	  [1] This needs the shell to define an appropriate routine to
	  return the text of the alias.  There is no requirement that such
	  a function exist.

	* Makefile: * Add user-controlled mk.conf variables	- SHLIBDIR
	      Location to install shared libraries if ${USE_SHLIBDIR}
			    is "yes".  Defaults to "/usr/lib".

		  - USE_SHLIBDIR  If "yes", install shared libraries in
	  ${SHLIBDIR}
				  instead of ${LIBDIR}.  Defaults to "no".
				  Sets ${_LIBSODIR} to the appropriate
	  value.
				  This may be set by individual Makefiles
	  as well.

		  - SHLINKDIR	  Location of shared linker.  Defaults to
	  "/usr/libexec".
				  If != "/usr/libexec", change the
	  dynamic-linker
				  encoded in shared programs

	  * Set USE_SHLIBDIR for libraries used by /bin and /sbin:
	  libc libcrypt libcrypto libedit libipsec libkvm libm libmi387
	  libtermcap libutil libz

	  * If ${_LIBSODIR} != ${LIBDIR}, add symlinks from
	  ${LIBDIR}/${LIB}.so*	 to ${_LIBSODIR}/${LIB}.so* for
	  compatibility.

	  * Always install /sbin/init statically (for now)

	  The net effect of these changes depends on how the variables are
	  set:

	    1.)   If nothing is set or changed, there is no change from the
		  current behaviour:
			  - Static /bin, /sbin, and bits of /usr/*
			  - Dynamic rest
			  - Shared linker is /usr/libexec/ld*so

	    2.)   If the following make variables are set:
			  LDSTATIC=
			  SHLINKDIR=/lib
			  SHLIBDIR=/lib
		  Then the behaviour becomes:
			  - Dynamic tools
			  - .so libraries used by /bin and /sbin are
	  installed to /lib,
			    with symlinks from /usr/lib/lib*so to ->
	  /lib/lib*so
			    where appropriate
			  - Shared linker is /lib/ld*so

	    3.)   As per 2.), but add the following variable:
			  USE_SHLIBDIR=yes
		  This forces all .so's to be instaleld in /lib (with
	  compat
		  symlinks), not just those tagged by their Makefiles to
	  be.
		  Again, compat symlinks are installed

	* readline/Makefile: Readability cleanups; MKfoo=no -> NOfoo.

2001-11-08 20:39  mycroft

	* term.c: In the `not what I asked for' department: Do NOT return
	  an error from term_init() if term_set() fails.  Otherwise
	  el_init() barfs and libedit fails to work.

2001-11-08 20:34  mycroft

	* el.c: Remove an unused variable.

2001-11-02 05:47  christos

	* el.c: If term_init() fails, cleanup and return NULL. This avoids
	  other lossage.  Pointed by charles.

2001-11-02 05:42  christos

	* term.c: Finish initializing all the term data structures even if
	  the terminal init fails. This makes editline work on dumb
	  terminals again. Noted by mycroft.  Oops, too agressive error
	  checking.

	* history.c: history_def_enter: fix off-by-one mistake in delete
	  condition (the behaviour to keep at least one entry on the
	  history list is retained) This fixes lib/9704 by Phil Nelson.

	  function via a new el_set() operation.  Thanks, nicely done :-)

2001-09-24 15:22  wiz

	* el.c: va_{start,end} audit: Make sure that each va_start has one
	  and only one matching va_end, especially in error cases.  If the
	  va_list is used multiple times, do multiple va_starts/va_ends.
	  If a function gets va_list as argument, don't let it use va_end
	  (since it's the callers responsibility).

	  Improved by comments from enami and christos -- thanks!

	  Heimdal/krb4/KAME changes already fed back, rest to follow.

	  Inspired by, but not not based on, OpenBSD.

	* readline/Makefile: Use relative path for symlink target so that
	  it won't point outside of tree.

2001-05-14 20:39  jdolecek

	* readline/Makefile: Back off previous and do differently: Ensure
	  that the <readline/history.h> link to <readline/readline.h> is
	  installed too for 'make includes'. Also, avoid creating obj dir.
	  This is finally real fix for lib/12929.  XXX Is this right?

2001-05-14 09:41  jdolecek

	* readline/Makefile: Use <bsd.inc.mk>, instead of <bsd.prog.mk>, so
	  that the readline.h header is installed during the 'make

	  ELRE_DEBUG, and change all occurences of ELRE_DEBUG(foo,bar,) ->
	  ELRE_DEBUG(foo,bar).	some compilers (e.g, gcc on darwin) bitch

	* el.c, readline.c: depoison the pure editline code from readline
	  compatibility hacks.

2001-01-05 22:15  jdolecek

	* Makefile, readline.c, readline.h, readline/Makefile,
	  readline/readline.h: Standard location of readline headers is
	  /usr/include/readline/, so install them there.  readline.h of
	  libedit had to move to subdirectory 'readline', due to the way
	  BSD makefiles work; this is better than potentially fragile
	  Makefile hacks

2001-01-04 16:56  christos

	* chared.c, hist.c, key.c, map.c, search.c, term.c, term.h,

	  a screen   * fix typo in _rl_qsort_string_compare, which caused
	  the list to not      be sorted after all

2000-12-30 23:46  jdolecek

	* term.c: term_beep(): if terminal supports both visual and
	  ordinary bell, 'ring' both

2000-12-23 23:07  jdolecek

	* shlib_version: bump libedit minor - added some public stuff for
	  readline emulation

2000-12-23 23:02  jdolecek

	* readline.c, readline.h: completion_matches(): fix a off-by-one
	  bug, fix variable name typo implement displaying of possible
	  completions, add hook to display the list	    on second
	  rl_complete() invocation in row (typically, double <TAB>)

	  This addresses the completion part of lib/11581 by Richard
	  Earnshaw.

2000-11-28 23:37  jmc

	* term.c: Alloc the keys structure with A_K_NKEYS as the multiplier
	  rather than a hardcoded value of 4.

	  A_K_NKEYS is currently 6 and this mismatch was stomping memory
	  when initializing the keys. (specifically gdb lost the exec file
	  name if it was a long path name).

2000-11-11 23:18  christos

	* chared.c, el.c, el.h, key.c, map.c, read.c, term.c, term.h: - add

	* el.c: pull up 1.18 (approved by thorpej).   allows a gdb linked
	  with libedit's readline emulation to work properly with xxgdb.

2000-08-02 05:36  chuck

	* el.c: make xxgdb and a gdb linked with libedit's readline
	  emulation work properly together.   xxgdb communicates with a gdb
	  running on a pty that it sets to -echo,-onlcr prior to forking
	  the gdb process.  GNU readline preserves the -echo setting while
	  libedit was undoing it (setting the tty to a sane state and
	  totally confusing xxgdb's parser).

	  this diff simply disables libedit if both readline emulation and
	  "stty -echo" are used/set.   that is enough to make xxgdb work
	  once again, but (XXX) this is not how GNU readline handles stty
	  -echo (it does not echo anything, but editing commands like
	  ^A,^K, etc.  still work), so the readline emulation isn't
	  perfect.

	  change reviewed by christos.

	  All praise lint :)

2000-03-10 13:55  jdolecek

	* readline.c: readline(): don't dereference NULL pointer if prompt

	* editline.3, el.c, el.h, histedit.h, prompt.c, prompt.h,

	  three years ago.  - implement EL_RPROMPT, which allows a
	  setting/getting of a function which	returns a string to be used
	  as the right-side prompt.  - improve HISTORY and AUTHORS sections
	  in editline(3).  - bump shlib minor version for EL_RPROMPT.

	  XXX: due to an implementation issue, the rprompt has a 1 space
	  gap before the      edge of the logical screen. editline's
	  logical screen is 1 space less      than the full screen width,
	  so there's a 2 space gap between the rprompt	    and the right
	  end of the physical screen. i'm not concerned about this.

	* read.c: In userland, pull in <errno.h> instead of <sys/errno.h>
	  for the declaration of errno.

1999-01-05 23:46  lukem

	* editline.3: fix history() prototype. (d@openbsd.org)

1998-12-20 18:52  kleink

	* histedit.h: Change multiple inclusion protection symbol name to
	  NetBSD convention which doesn't violate namespace rules.

1998-12-12 21:08  christos

	* chared.c, chared.h, common.c, el.c, key.c, map.c, parse.c,
	  read.c, refresh.c, search.h, term.c, tokenizer.c, vi.c: delint

1998-12-12 20:54  christos

	* readline.c: many problems; variables hidden by others, size_t <->
	  confusion

1998-12-12 20:52  christos

	* history.c: - missing error message from array could cause core
	  dump - delint

1998-12-03 18:51  cgd

	* history.c: per e-mail with christos: history_next_event() should
	  return -1, not NULL, in case of error, just like
	  history_prev_event() does.

1998-09-28 13:00  christos

	* el.c: fix core-dump caused by maps not being initialized before
	  tty is called.

1998-09-27 20:04  christos

	* tty.c: Obey incoming tty char settings.

1998-09-02 23:33  christos

	* search.c: PR/6081: Wolfgang Helbig: search broken in vi mode.
	  When patbuf was changed to be dynamically allocated, sizeof was
	  not changed appropriately.

1998-07-29 04:26  lukem

	* Makefile, editline.3, editrc.5, el.c, el.h, histedit.h, map.c,
	  map.h, parse.c, prompt.c, prompt.h, shlib_version: * add more
	  checks for NULL pointers in passed arguments * implement
	  el_get(EditLine *, int op, void *result), which does the
	  inverse of el_set() * add EL_EDITMODE operation to el_set and
	  el_get; if non zero editing	is enabled (the default).  * add
	  "edit  on | off" editrc command, which modifies EL_EDITMODE.
	  users can now add '*:edit off' in ~/.editrc as an advisory to
	  disable editing.

	  NOTE: at this time EL_EDITMODE is just an indication of the state
	  of the 'edit' command. It's up to the application to check this
	  after el_source() or el_parse() to determine if editing is still
	  required.

1998-06-08 12:56  lukem

	* editline.3: documentation is always probably incomplete; don't
	  make an issue of it

1998-06-01 16:31  lukem

	* editline.3, histedit.h, read.c, shlib_version: * implement
	  CC_REFRESH_BEEP; as per CC_REFRESH but beep as well. this   is
	  useful in completion when a partial completion is found * remove
	  entry in BUGS about el_parse(); that was fixed a while ago

1998-05-20 03:38  christos

	* TEST/test.c: Show the simpler way.

1998-05-20 03:37  christos

	* editline.3, histedit.h, history.c: Add H_APPEND to simplify the
	  interface.

1998-05-20 03:12  christos

1998-05-20 03:04  christos

	* tty.c, tty.h: change M_* constants to MD_* to avoid clashes with
	  <stream.h>

1998-05-20 03:04  christos

	* term.c, term.h: remove term_beep hack.

1998-05-20 03:03  christos

1998-05-20 03:03  christos

	* readline.c: Adjust to the libedit api changes.

1998-05-20 03:02  christos

	* history.c: Add a function to be able to set the cursor to a given
	  event number.

1998-05-20 03:02  christos

	* histedit.h: - add extra argument to el_init - fix history
	  functions - add el_beep()

1998-05-20 03:01  christos

	* emacs.c, refresh.c: cast is*() arg to unsigned char

1998-05-20 03:01  christos

	* el.c: el_init takes a third stream argument and add el_beep.

1998-05-20 03:00  christos

	* common.c: Don't print to stderr, but to the editline error
	  stream.

1998-03-30 03:30  mrg

	* map.c, tty.c: use int rather than char as an array index.

1998-02-05 19:51  perry

	* editline.3: add LIBRARY section to man page

1998-02-03 20:12  perry

	* chared.c, common.c, emacs.c, map.c, vi.c: remove obsolete
	  register declarations

1998-01-30 03:27  perry

	* term.c: update to lite-2 (just an sccsid change)

1998-01-30 03:18  perry

	* term.c: import lite-2

1998-01-21 12:12  lukem

	* editline.3, parse.c: in el_parse(), use a temporary buffer to
	  store the program name when comparing, preventing trashing of
	  argv[0]. remove note in man page warning of former behaviour.

1998-01-21 11:12  lukem

	* read.c: fix compile errors if FIONREAD is defined.  noted by
	  David Holland <dholland@bordeaux.eecs.harvard.edu> in [bin/4012].

1998-01-05 08:41  perry

	* shlib_version: RCSID Police.

1997-12-20 20:15  christos

	* el.c, el.h, read.c: Small optimization. Don't call isatty() on
	  every invocation of el_gets, but remember if the tty setup
	  failed... Also trim the input line of trailing \r's.

1997-11-13 05:48  thorpej

	* term.c, term.h: Un-"protect" term_beep() and rename it to
	  __term_beep() to keep it out of the user's namespace.  We need to
	  do this because the readline emulation functions call
	  term_beep(), but readline isn't built using the same (funky)
	  namespace-protection method as the rest of libedit (it's included
	  like a normal library object).

	  Without this (fairly disgusting) hack, any program linked against
	  libedit will fail to link with an unresolved reference to
	  term_beep() if using an Elf toolchain (e.g. on the Alpha).

	  XXX Why this doesn't happen with NetBSD's a.out toolchain is a
	  mystery XXX to me, and I'm not sure I really want to know (given
	  that a.out XXX _should_ break the same way as Elf does in this
	  case).

1997-11-13 05:43  thorpej

	* Makefile: Build readline.o into debugging versions of libedit,
	  too.

1997-11-12 22:56  thorpej

	* readline.c: el_gets() takes an int *, not a size_t *.

1997-11-09 01:53  lukem

	* Makefile: Make a link for history.h -> readline.h

1997-10-24 00:51  christos

	* readline.c, readline.h: Const de-poisoning :-( Unfortunately the
	  default gnu readline does not have full prototypes... With those
	  changes, and a single line change in gdb/top.c, gdb links with
	  -ledit

1997-10-24 00:24  christos

	* Makefile, readline.c, readline.h, shlib_version: PR/4301: Jaromir
	  Dolecek. Add gnu-readline wrapper for editline.

1997-10-23 08:35  lukem

	* TEST/test.c: make this compile with the new libedit history()

	  Studenmund.

1997-10-14 17:05  christos

	* editline.3, hist.c, hist.h, histedit.h, history.c, shlib_version:
	  PR/4257: Jaromir Dolecek: history() has no generic error handling
	  and isn't reentrant. This changes the interface of the history
	  function, so we need a major number bump.

1997-10-13 18:09  lukem

	* term.c: use <termcap.h> instead of "termcap.h" (which was
	  repository copied to libterm)

1997-10-13 17:46  mrg

	* termcap.h: termcap.h moves to libterm.

1997-10-09 21:16  christos

	* tty.c: PR/4211: Dave Huang: don't lose VSTATUS and VEOL and any
	  other characters that are VDISABLED by default.

1997-10-09 16:36  lukem

	* Makefile: - define WARNS?=1 in the top-level Makefile.inc, and
	  don't define	 anywhere else.  - for now, override WARNS=0 in
	  librpcsvc and libwrap, until they're	 cleaned up - rcsid police

	  lib is now clean (except for librpcsvc and libwrap) on the i386,
	  and this should motivate the other ports to fix any other minor
	  problems that their compilers pick up that the i386 version
	  doesn't.

1997-07-31 01:57  jtc

	  indenting fooled me)

1997-01-14 05:17  lukem

	* common.c, editline.3, histedit.h, read.c: Implement CC_REDISPLAY,
	  which (unlink CC_REFRESH) redraws the entire input line (a la
	  ^R). This is useful if the binding outputs information and mucks
	  up the input line. To be used in ``list-choices'' bindings (refer
	  to the ^D binding in csh when filec is set)

1997-01-11 10:57  lukem

	* editrc.5, parse.c: * document ^char and \ escape sequences * when

1997-01-09 14:12  lukem

	* Makefile, editline.3, editrc.5, parse.c: * add a man page for the

	  functions  are used if REGEX is defined, V8 regular expresion
	  functions are used if REGEXP is defined, and BSD regular
	  expression functions are used if neither are defined.  And
	  defined REGEX in sys.h so that programs using libedit don't have
