[PATCH] builtin-branch - allow deleting a fully specified branch-name

This change allows, for instance
	git branch -d refs/heads/foo
to succeed. Without this patch, the code just assumes that the
given branch name should be appended to "refs/heads" or
"refs/remotes", thus attempting (and failing) in the above case
to delete "refs/heads/refs/heads/foo"
