May not be relevant to this patch per-say, but is there a way to have the completion for checkout only complete up to a part of remotes/branches? Say a forward-slash '/'. For example git.git has lots of branches which have the form: origin/<initials>/branch-name. It would be convenient if when I type:

git checkout <TAB>

Instead of getting a long list of 2k or so branch names that instead I would get see the remote's name e.g. 'origin/' kind of like vanilla directory completion. This way, unless I'm actually interested in the remote, I don't see the thousands of branches related to it.
