   This strikes me as something that *really* ought to be in the
documentation.  Admittedly, I haven't done a lot of work with
tree structures, and perhaps this is something that's just a
given among those who use this technique a lot.  Still, to me it
is *not* intuitively obvious that this is a problem.

   Yeah, I already did this.  This was my third attempt to post my
question and the only successful one.  In the interim, I did just
the technique you suggested.  Works fine.
