branch: allow a no-op "branch -M <current-branch> HEAD"
Overwriting the current branch with a different commit is forbidden, as it will make the status recorded in the index and the working tree out of sync with respect to the HEAD. There however is no reason to forbid it if the current branch is renamed to itself, which admittedly is something only an insane user would do, but is handy for scripts. Test script is by Conrad Irwin.
