zsh-3.0-pre5 released

[Zoltan Hidvegi <hzoli@xxxxxxxxxx>]

-----BEGIN PGP SIGNED MESSAGE-----

Hopefully this will be the last pre-release before zsh-3.0.  If you think
that that an essential patch is still missing or there is a serious bug
which should be fixed immediately, do not hesitate to mail it to
zsh-workers@xxxxxxxxxxxxxxx.  Do not mail bugreports and fixes directly to
me.

In this release all kind of special parameter assignemnts should work
properly both before external commands and before shell builtins/functions.
This means the the common IFS=something read ...  phrase will work as in sh
without changing IFS globally.  For external commands foo=bar somecommand
will work even if foo is read-only or array or integer.  This introduces a
slight incompatibility: USERNAME=name command no longer works to start a
command under a different UID (of course this never worked for
non-privileged users).  (USENAME=name ; command) should be used instead.
The advantage of this is that it works for builtins and shell functions as
well as external commands.

EUID, EGID, UID, GID, USERNAME, histchars, HISTCHARS and IFS are no longer
inported from the environment to improve security.

The malloc() debug routines in mem.c are improved a little bit.  Developers
and beta-testers my find it useful to configure zsh with

./configure --enable-zsh-{mem,{mem-,}debug,secure-free}

This will create a bigger and slower executable but it may catch some
hidden bugs.  Unfortunately it does not work on all systems.

The texinfo documentation is finally really up-to-date.  For those who do
not have the necessary tools to process texinfo there is precompiled
documentation in zsh-doc.tar.gz in PostScript, dvi, info and html formats.
It also contains the PostScript and plain text version of intro.ms but that
hasn't been updated since the release of zsh-2.5.0.

See the ChangeLog for the full list of the changes.

The new release can be found on the following anonymous ftp sites.  The
first is the official archive site.  The rest are mirror sites which are
kept frequently up to date.  The sites maked with a star may mirror
ftp.math.gatech.edu instead of the primary site.

zsh-3.0-pre5.diff.gz and you do not need to download the full source.
To do this just cd into the directory where the zsh-3.0-pre4 sources are
kept and issue

gzip -dc zsh-3.0-pre5.diff.gz | patch -p
touch stamp-h.in configure
