Oops, sorry. We need to reset LC_ALL.
I didn't know _comp_locale; is it documented somewhere?

Might be, but I'm not sure.

zsh% tar --<TAB>

gives a list of long options with localized description, because the output
of 'tar --help' is localized and _tar uses '_arguments --' for completing
long options. Although the localized description may not be "perfect", some
user would still want to see it.

How about adding an option (say -l) to _call_program so that _comp_locale
is called before the command?
