That worked, except I was trying to keep from having an "extra" output
record inserted that with-output-to-output-record makes.  When the
original output is performed, there is not this extra output record.
I suppose I could maybe think of a way to avoid this or just use the
children of the new output record.

Anyways, it seems as if Scott is making the right fix.
