3.1.6-pws-6

[Peter Stephenson <pws@xxxxxxxxxxxxxxxxx>]

Since there's no point waiting for Sven's weekend patches, I have uploaded
http://www.ifh.de/~pws/computing/zsh-3.1.6-pws-6.tar.gz

with the changes listed below.

This will probably be the last for a few weeks, as I am leaving on Friday
and I'm not sure when I'll reappear, though in the first instance at least
I should be able to get back online quite quickly.  If the backlog gets too
big someone else can produce an intermediate version.

	* pws: Config/version.mk: 3.1.6-pws-6

	* pws: 8051: Completion/User/_users_on: typos.

	* pws: 8050: Src/utils.c: getkeystring() used in ##<char>
	  (formally #\<char>) should return unsigned char.

	* pws: 8049: Src/math.c: use HEAPALLOC for math evals.

	* Adam: 8048: Completion/User/_my_accounts,
	  Completion/User/_other_accounts, Completion/User/_rlogin,
	  Completion/User/_ssh, Completion/User/_users_on: use
	  my_accounts and other_accounts for ssh and friends;
	  user users for write and potentially elsewhere.
	
	* Adam: 8047: Completion/User/_users: lasts uses _users.

	* Tanaka Akira: 8044: Completion/Base/_regex_arguments,
	  Completion/Debian/_apt: remove NULs from cache files,
	  fix some typos.

	* Tanaka Akira: 8042: Doc/Zsh/expn.yo, Src/subst.c, Src/utils.c:
	  ${(qqqq)...} now does $'...' quotation; rejigging unprintable
	  characters is now ${(V)...}.

1999-09-24  Peter Stephenson  <pws@xxxxxxxxxxxxxxxxx>
	* Tanaka Akira: 8039: Src/utils.c: quoting of backslashes inside
	  ${(qqq)...}.

	  beginning with a ~.

1999-09-23  Peter Stephenson  <pws@xxxxxxxxxxxxxxxxx>

	* pws: 8033: Src/math.c: use '##' to get code for literal
	  character as less error-prone than `#\'.

	* Sven: 8030: Src/utils.c: 8019 needed to expand the buffer
	  even more.

	* pws: 8026: Src/math.c: idiotically made buffer too short
	  for error message.

	* Sven: 8023: Src/subst.c, Src/utils.c, Doc/Zsh/expn.yo:
	  ${(qqqq)...} quotes unprintables in bindkey fashion.

	* pws: 8022: Src/Zle/zle_misc.c: digit argument with metafied
	  digits didn't work.

	* Sven: 8021: Src/Zle/complist.c: keep better track of cursor
	  position when moving in a menu selection.

	* Vin Shelton and pws: 8020: Src/Zle/deltochar.c,
	  Doc/Zsh/mod_deltochar.yo: new zap-to-char, uses deltochar()
	  function but doesn't delete last occurrence (replaces 8010).

	* Sven: 8019: Src/utils.c: buffer overflow quoting newlines.

	* Sven: 8015: Completion/Commands/_history_complete_word,
	  Src/Zle/zle_tricky.c:  bug without history_stop in
	  _history_complete_word; go backwards on line when scanning
	  history words.

	* pws: 8014: Src/math.c: arguments after the first in math
	  function skipped first character.

	* Sven: 8013: Completion/X/_x_keysym, Completion/X/_x_modifier,
	  Completion/X/_xmodmap: completion for keys and modifiers
	  in xmodmap.

	* Sven: 8012: Doc/Zsh/compsys.yo: document
	  incremental-complete-word configuration keys.

	* Sven: 8011: Src/Zle/comp.h, Src/Zle/complist.c,
	  Src/Zle/zle_tricky.c: better menu insertion with braces.

1999-09-22  Peter Stephenson  <pws@xxxxxxxxxxxxxxxxx>

	* Sven: 8004: Src/Zle/complist.c, Src/Zle/zle_tricky.c,
	  Doc/Zsh/compctl.yo, Doc/Zsh/compwid.yo: crash in selecting;
	  documentation for 8001.

	* Sven: 8001: Src/Zle/comp.h, Src/Zle/compctl.c,
	  Src/Zle/zle_tricky.c, Doc/Zsh/compctl.yo, Doc/Zsh/compsys.yo,
	  Doc/Zsh/compwid.yo, Completion/Core/_description: -1 and -2
	  flags to completion commands allow removal of consecutive and
	  non-consecutive duplicates.

	* pws: 7999, 8000: Doc/Makefile.in, Doc/Zsh/guide.yo,
	  Doc/Zsh/mod_mapfile.yo, Doc/Zsh/mod_mathfunc.yo,
	  Doc/Zsh/modules.yo, Doc/Zsh/mod_parameter.yo,
	  Src/Modules/mathfunc.c, Src/Modules/mathfunc.mdd, Src/math.c:
	  mathfunc module, contains 46 functions for use in math
	  evaluations; make function arguments behave like normal mathevals.

	* Sven: 7998: Src/Zle/comp.h, Src/Zle/complist.c,
	  Src/Zle/zle_tricky.c, Src/options.c, Src/zsh.h,
	  Doc/Zsh/options.yo: Display column sizes can be different
	  for different completion groups; LIST_PACKED and LIST_ROWS_FIRST
	  options change listing display behaviour; clean functions up.

	* pws: 7995: Completion/Builtin/_zmodload: when looking for module,
	  restrict to *.s[ol].

	* Tanaka Akira: 7989: Completion/Base/_combination,
	  Completion/Debian/_apt, Completion/Base/_regex_arguments,
	  Doc/Zsh/compsys.yo: document _combination and _regex_arguments,
	  clean up relevant completion functions.

1999-09-21  Peter Stephenson  <pws@xxxxxxxxxxxxxxxxx>

	* Sven: 7985: Src/Zle/zle_tricky.c: crash in old completion
	  with non-existent file.

	* pws: 7983: Src/hist.c: bug that hungetc() blindly went
	  ahead after keyboard interrupt fixed by testing for errflag
	  in hungetc().

	* pws: 7981, 7982: Src/math.c, Src/zsh.h: use dupstring()
	  instead of lvalue stack; better ternary expression parsing;
	  old `unbalanced stack' messages shouldn't show up so become
	  debugging messages; arithmetical errors in unevaluated
	  portions don't cause shell errors.

	* Sven: 7978: Src/exec.c, Src/init.c, Src/utils.c: grow and shrink
	  underscore parameters properly.

	* Sven: 7976, 7977: Src/builtin.c, Src/math.c, Src/mkbltnmlst.sh,
	  Src/mkmakemod.sh, Src/module.c, Src/zsh.h, Src/Modules/example.c,
	  Src/Modules/example.mdd, Doc/Zsh/arith.yo, Doc/Zsh/builtins.yo,
	  Etc/zsh-development-guide: system for loading math functions
	  for use in math evals.

	* Sven: 7974: Src/Zle/zle_tricky.c: remove duplicates.

	* Bart: 7968: Completion/User/_mailboxes: mutt fixes.

1999-09-20  Peter Stephenson  <pws@xxxxxxxxxxxxxxxxx>

	* pws: 7963: Src/math.c, Src/subst.c: better error checking
	  for math evals; don't pass surrounding parentheses down for
	  $(( ... )).

	* Adam: 7961: Completion/User/_mailboxes: fun with variables and
	  elm.

	* Sven: 7960: Src/Zle/zle_tricky.c: too much deleted in path
	  completion.

	* Sven: 7959: Completion/Core/_path_files, Doc/Zsh/compsys.yo:
	  fixes from previous patches which missed 3.1.6-pws-5.

	* pws: 7957: Src/module.c: `zmodload -e modname' in statically
	  linked shell didn't work.
