Thanks for looking at this again, and thanks for fixing that problem.

I've attached an updated patch which incorporates your change, and
also another 2 small tweaks that I made after making another pass over
this myself.

None from me. I think it's had plenty of review time over the last year.

The only other thing I can possibly think of is to apply most of the
analyzejoins.c changes as a refactor patch first. If committer wants
that, I can separate these out, but I'll hold off for a response
before doing that.
