pushglobs

Hello,

The glob support in the fetches has gone down so well that I'm looking into doing the same for pushrefs.

The push work is done in C; so there is obviously no globbing support from the shell. I know that git does globbing in other places, so wanted to ask if it's appropriate to use that rather than me write my own hacked up version?

The context is this: I'm extending builtin-push.c:add_ref() to catch globbed refs and then recursively expand them.
