[PATCH] Completion batch #1: Add some g-prefixed GNU variants

[dana <dana@xxxxxxx>]

I mentioned the other day that i was sitting on a bunch of completion changes.
Most of them are new functions, but some are improvements to existing ones. I
think i'll submit them in batches so the review work isn't too overwhelming. Let
me know if there's any way i can make it easier though.

Batch 1 is easy: I just updated several functions to include the g-prefixed
command names used for GNU variants on systems like macOS+Homebrew.
