Thanks, I did not think of this.

I pondered about `git name-rev` but failed to figure out how to make it accept just "HEAD" as the point of reference. Passing it "--refs=HEAD" (or "--refs HEAD", FWIW) does not appear to do what I'd expect it to: a couple of top commits are not annotated at all, and then they start to get annotated relative to "origin/HEAD". Note that I've tested this on a detached HEAD which contains an unmerged line of history.
