Yes, this was what I was afraid of; an introduced regression in the RC 2-to-3 period, which IMO makes the bug a bit more serious. Also, this bug in particular looks like it manifests in a fairly nasty way, and having it catch people for the final release seems a bit worrisome.
I also just remembered that the Haddock documentation for 7.10.1 is still broken; I've been tracking the bug today, but I need to sync up with the Haddock maintainers to discuss more. I really think this one needs to be fixed. So I also suggest we postpone for a few days to fix these two things, if possible.
