Pushed. Yay!

There's one sgml comment you'd added:
"Furthermore, nested set-returning functions did not work at all."

I'm not quite sure what you're referring to there - it was previously
allowed to have one set argument to an SRF:

postgres[28758][1]=# SELECT generate_series(1,generate_series(1,5));
┌─────────────────┐
│ generate_series │
├─────────────────┤
│ 1 │
│ 1 │
│ 2 │
│ 1 │
│ 2 │
│ 3 │

Am I misunderstanding what you meant? I left it in what I committed,
but we probably should clear up the language there.

Working on rebasing the cleanup patch now. Interested in reviewing
that? Otherwise I think I'll just push the rebased version of what I'd
posted before, after making another pass through it.
