compat-drivers: allow git-paranoia to work on current directory

This allows you to run git-paranoia on your current directory.
It will return 0 if everything is squeeky clean. This is useful
if for example you want to run a cronjob to update git trees but
never update them if you have any deltas in place of any kind.
