Move git-tracking check into diff command.

Browse Source 
This avoids shelling out twice per buffer: once to check whether git
knows about the file and once to perform the diff.  Now we simply do
both in one external call.

Profiling showed external calls to git taking ~20ms.  This doesn't seem
too bad but it adds up.
