Re: Bug#482662: zsh: completion with locate gives extra output

["Jun T." <takimoto-j@xxxxxxxxxxxxxxxxx>]

I want take this opportunity to make it support MacOSX.
I believe this will work on (free|Open)BSD as well.

NOTES: 
(1) this includes the patch by PWS, which is not yet committed.

(2) I'm not sure if we should 'setopt EXTENDED_GLOB' at the top
of this script. (the globbing flag (#i) requires the option).

(3) I used '_arguments -S' also for mlocate and slocate.
Should it be used also for gnu locate?

(4) '_arguments -A' is used only for bsd locate, since mlocate/slocate
accepts options after pattern(s).
