If "git init" fails after it created the directory, it will be left
behind because test_when_finished hasn't been called yet.  The same
problem exists in the other hunk.  Moving it above "git init" may
trigger "rm -rf X" where X does not exist yet, but that is what you
are giving the 'f'orce option there for.

Not a huge deal and no need to resend only to fix them alone,
though.
