Should probably just add a hook in there somewhere. Maybe. Or a 'gitpath' property or something:

'gitpath' => dirname( DIR ),

And then check both (with gitpath having priority over path) for which to use

Change I8e6fe417: (Bug 43986) Check parent directory for the .git directory

GitInfo newer checks the directory, it just assumes it to be correct.

This should be handled in some other way.
