[PATCH v4] zsh localedef completion

[Marko Myllynen <myllynen@xxxxxxxxxx>]

Hi,

Below is zsh completions for the localedef(1) command, I've tested this
on RHEL 7 against the glibc provided localedef command. Otherwise it
works nicely but I'm a bit wondering one thing here (not two anymore -
thanks to Daniel Shahaf for explaining the other one):

$ localedef -c<TAB>

offers also V/? although I hoped them to get excluded in that case.

As Eric Cook pointed out, there's life outside of GNU and this patch now
supports many non-GNU variants as well. Since I don't have access to a
Solaris system I didn't implement that yet, would be probably pretty
straightforward but would be good to actually test it.

Baptiste Daroussin informed that even though there's no FreeBSD man
page for localedef(1) yet, it will be based on the same code as the
Dragonfly BSD variant in FreeBSD 11.

As with locale(1) completion, I chose to duplicate few lines so that if
something needs to be changed for non-GNU which I haven't tested, it's
probably easier to tweak the already separate if-block then.
