[PATCH v2] zsh locale completion



Hi,

Below is zsh completions for the locale(1) command, I've tested this on
RHEL 7 against the glibc provided locale command. Otherwise it works
nicely but I'm a bit wondering why after "locale -a<TAB>" I'm getting
all other options offered, I would have thought getting -v offered only.

On Eric Cook's suggestion supports now GNU/OpenBSD/POSIX. I duplicated
the category/keyword handling under GNU/POSIX sections as I don't have
any non-GNU systems to test on and if any changes are needed for non-GNU
it's probably easier to tweak the already separate if-block then.
