I don't think Nathan explicitly tried to backport anything.  This
looks to me like AUTOSEL maybe took a commit message from a different
commit, and applied it to this diff.

ie. I don't think this is a bug in a manual backport, I think AUTOSEL
did something funny and created a backport with commit message A but
commit diff B.
