Hmm, sorry, two of them were indeed reverted. I simply didn't remember, and
checked only for patches authored by you. Patch 1 wasn't reverted, though?

And then, as to patch 2 (which was the problematic one): Why did you retain
Anthony's R-b? In the v7 discussion I see no indication of him to keep the
tag with the change in place. Which (generally) is taken to mean the person
wants to take another look before possible re-offering the tag. With a bug
fixed, all R-b covering that area become invalid (unless explicitly
indicated otherwise).
