This is not the sort of answer I was hoping for.
I was hoping you'd say "when someone runs 'hg foo', Mercurial does
stupid thing X because of Y."
Then I can say "yes, that sounds like a serious bug and now I know
enough about what the patch is trying to do to review it and test it".
Otherwise you have to wait for the nonexistant person who is an expert
in both the caching system and the repo filtering to show up to
understand your patch.
Mathematics is the supreme nostalgia of our time.
