rev-parse --glob

Browse Source 
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.
