[PATCH 2/2] Clean up "git-branch.sh" and add remove recursive dir test cases.

[Christian Couder <chriscool@tuxfamily.org>]

Now that directory recursive remove works in the core C code, we
don't need to do it in "git-branch.sh".

Also add test cases to check that directory recursive remove will
continue to work.
