update: fix bare --clean to work on new branch (issue5003) (BC) Before this commit bare update --clean on newly created branch updates to the parent commit, even if there are later commits on the parent commit's branch. Update to the latest head on the parent commit's branch instead. This seems reasonable as clean should discard uncommited changes, branch is one of them.
