I've pushed the v3 patch with a lot of editorial work (e.g. cleaning
up comments you hadn't). I still want to think about getting rid of
some of the "extraneous" bitmapsets and lists that are running around
here ... but time grows short before beta3, and it's not clear that
that would be appropriate material to push into v11 anyway.

I didn't include this change because (a) it's late, (b) no test
case was included, and (c) I don't entirely believe it anyway.
How would a rel be both leaf and nonleaf? Isn't this indicative
of a problem somewhere upstream in the planner?
