rev-parse --glob
Add --glob=<glob-pattern> option to rev-parse and everything that accepts its options. This option matches all refs that match given shell glob pattern (complete with some DWIM logic). Example: 'git log --branches --not --glob=remotes/origin' To show what you have that origin doesn't.
