FWIW, I am not excited about a backpatch, so I would keep this as a
HEAD-only change.  Sure, the existing behavior is incorrect, but it
would be more annoying to break somebody's script flow after a minor
release.  And that's not critical.

(If you want to fix that yourself, please feel free.  I can do that
tomorrow by myself but life keeps me busy today and I don't have any
room to keep an eye on the buildfarm.)
