Heh, I meant necessary as in "Oops, I probably just completely broke

OK, that was my reading, as well; thanks for confirming.

And here is a test that I believe triggers the problem (fails with my
patches, succeeds with your fix):

I wonder if we could make this a bit cleaner by actually using the git
