Ah, this somewhat addresses my reply to the previous patch.
I think by rearranging and/or squashing the patches, they could tell a
more coherent story, and cause less confusion.

(Basically: avoid creating conditions where the code is wrong — if a
 later patch is needed in order to make a previous patch correct, but the
 later patch alone wouldn't make the code incorrect, swap them. If there's
 breakage either way and you can't tease them apart, squash them together.)



Thanks,
Jonathan
