Veni, Vidi, VISA

I've uploaded version 4.3.3 of zsh to ftp.zsh.org.  If there aren't

complaints too loud I'll send it to Sourceforge and announce it on

Freshmeat tomorrow.  (This time I remembered to check that all functions

are exported where necessary, so we shouldn't have the traditional round

of mod_export additions.)



Release notes (note I didn't hunt too hard for new features, so please

tell me if there's something interesting I missed):



Version 4.3.3 now contains most of the planned support for multibyte

characters.  There are still some problems notably with Unicode combining

characters and composition of characters (notably on MacOS).  Some

expertise in these areas would be useful.  If support is available the

shell will be compiled with multibyte support and will start in multibyte

mode (option MULTIBYTE set).



Apart from the usual bug fixes and enhancements to completion functions,

there are various other new features:



- Users can write shell functions to be used in mathematical expressions.

  See the description of "functions -M" in the zshbuiltin manual page

  and the description of zmathfuncdef in the zshcontrib manual page.

- The zle widget read-command reads a key sequence without executing it.

- The zle widgets auto-suffix-remove and auto-suffix-retain provide

  user-defined control for suffixes (on the lines of AUTO_REMOVE_SLASH).

- Various arrays are available to add a named function to a set

  called where the specific functions chpwd, periodic, precmd and preexec

  are called.  The arrays are called chpwd_functions, etc.  There is a new

  special function zshexit also with a corresponding hook.  See SPECIAL

  FUNCTIONS in the zshmisc manual.

- ";|" at the end of a case statement causes the shell to continue

  looking at later tests (c.f. ";&" which causes an unconditional fall

  through).

- The sched builtin has been enhanced to run events asynchronously

  when the shell is waiting at an interactive prompt.

- There is a new set of functions to handle calendars and dates.

  See the zshcalsys manual page.

- The zsh/parameter module makes available the parameter functrace

  for function backtraces.
