[PATCH 1/2] Add tests for git-prune

[Michele Ballabio]

It seems that git prune changed behaviour with respect to revisions added
from command line, probably when it became a builtin. Currently, it prints
a short usage and exits: instead, it should take those revisions into
account and not prune them. So add a couple of test to point this out.

This is a resend, with some minor changes and a follow-up.
I'm still not sure if
	mv .git/logs .git/logs.old
should be moved outside of the test or not.
