update a few Porcelain-ish for ref lock safety.
This updates the use of git-update-ref in git-branch, git-tag and git-commit to make them safer in a few corner cases as demonstration. - git-tag makes sure that the named tag does not exist, allows you to edit tag message and then creates the tag. If a tag with the same name was created by somebody else in the meantime, it used to happily overwrote it. Now it notices the situation. - git-branch -d and git-commit (for the initial commit) had the same issue but with smaller race window, which is plugged with this. Signed-off-by: Junio C Hamano <>
