The latter should read "HEAD@{either reflog or -1 or 'upstream'}"

Or do we make HEAD@{upstream} to mean "deref HEAD to learn the
current branch name and then take its upstream"?  If so @@{upstream}
might logically make sense, but I do not see why @{upstream} without
HEAD or @ is not sufficient to begin with, so...
