Handling of LANG (and other LC_*) in zsh.

[Andrej Borsenkow <borsenkow.msk@xxxxxx>]

Hi!

I already mentioned this problem; now I try to provide patch for it ;-)

Environment: zsh-3.0-pre2
Problem: if LANG is changed, zsh tries to change its locale by using
setlocale(LC_ALL, <value of LANG>). Alas! it breaks normal handling of
locale: if any of LC_* is set, it overrides LANG setting.

I tried to solve it in some portable (IMHO;) way: when any of LANG or LC_*
variables is changed, it is put in zsh environment and
setlocale(LC_ALL,"") is called; it should have the same effect as setting
variable in environment *before* starting zsh.

I put all LC_* there; it doesn't hurt even if on some systems they are not
used, does it?

I am not member of this list; so I would appreciate any Cc of you comments
on my suggestion. 

Diffs attached

greetings
