It's the current branch, as returned by "git symbolic-ref HEAD".

Yes.

Sorry for the confusion. We're using "symbolic-ref HEAD" to get the
above information. I was just trying to explain why we're dealing with
ref names that contain a "refs/heads" substring (like
refs/wip/wtree/refs/heads/master in the example I gave).

Our use of name-rev is just to get a friendly name for a hash. If two
branches point to the same commit, we're fine with whatever decision
"git name-rev" makes; we just want to limit it to refs in the
"refs/heads/" namespace.
