Because "test_commit five" creates a commit and point it with a tag 'five', doing so on a branch whose name is 'five' will later result in an 'ambiguous refs' warning. Even though it is harmless because all the later references are for the tag, there is no reason for the branch to be called 'five'. Give it a name that describes its purpose more clearly, i.e. "newroot". Signed-off-by: Junio C Hamano <gitster@pobox.com>
