Oh, that sounds quite the right way. Clever.

So, my original question is answered as "yes, you can merge in changes
from mainline, and 'create patch' will work as it should".

Good!!. Thanks!!!.

Publish out somewhere would be useful, I guess. This is a problem I
have found in a few other projects. I can see even a modifier for "hg

Could be implemented as a command line command using "revsets"?.
Propose a new revset to mercurial devels?
