PATCH: Restore `LC_ALL' when setting `LANG'

[Frank Terbeck <ft@bewatermyfriend.org>]

(Cc:ing Upstream)

When setting LANG, zsh sets LC_ALL and then goes on to restore all
interesting LC_* values after that. Up to now, it did not restore LC_ALL
itself, though.

That could lead to trouble when setting LC_ALL=something-utf8-ish and
after that LANG=something-non-utf8.

This was reported in Debian bugreport #654225:

  <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=654225>

A recipe to reproduce the issue is here:

  <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=654225#65>

I think the patch below fixes the issue correctly, by restoring LC_ALL
from its parameter along the way with all the other LC_* values zsh
cares about.

(FWIW, the test-suite still passes with this change.)

Regards, Frank
