Since pull and fetch are done often against the same remote repository repeatedly, keeping the URL to pull from along with the name of the head to use in $GIT_DIR/branches/$name makes a lot of sense. Adopt that convention from Cogito, and try to be compatible when possible; storing a partial URL and completing it with a trailing path may not be understood by Cogito. While we are at it, fix pulling a tag. Earlier, we updated only refs/tags/$tag without updating FETCH_HEAD, and called resolve-script using a stale (or absent) FETCH_HEAD.
