StGit command completions - and Git ones?

I noticed in your TODO you talk about adding command line completions. I've been doing it for my needs, and the thing is still very incomplete, even if it's not a "XXX hack hack hack", and I wanted to send this first draft.

Note: I've not tried to add any completion which isn't StGit specific:
a) I didn't need them

b) they should be implemented for git and cogito first

c) not everything is clear. For instance, I think that SHA1 completion is pretty useless (I never type a SHA1), while only branch and tag completion is, but maybe other disagree: there's support for it in Cogito, in fact, and a shortened SHA1 is used as kernel revision.

Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
