I just read `git help merge` again and I think the solution is 'git
checkout 13 && git merge --strategy ours 13.19.0-rc1'. This would
effectively tell git that '13' already contains 13.19.0-rc1, but without
actually trying to pull any changes to 13. This merge would be the
final step of mkrelease.py.
No changes will be needed to our handling of '.lastclean', please ignore
those comments as I was wrong.
