Well, it's nearby anyway. I've committed the present patch (with a
number of fixes). While I was looking at it I came across several
things in the existing code that I think are either wrong or at least
inadequately documented --- the above complaint is just the tip of the
iceberg. I'm going to make another pass over it to see if I'm just
missing things, and then report back.
