rev-parse --branches/--tags/--remotes=pattern

Since local branch, tags and remote tracking branch namespaces are
most often used, add shortcut notations for globbing those in
manner similar to --glob option.

With this, one can express the "what I have but origin doesn't?"
as:

'git log --branches --not --remotes=origin'
