Ah, so that's the culprit.  Thanks!

Indeed, that does seem to work: outline-next-heading returns nil if it
doesn't find a next heading, and a buffer location otherwise (at least
that's the way it looks based on some tests; the documentation doesn't
say, and I didn't crack open the code).  So wrapping the rest of the
lambda body in (if org-map-continue-from ...) prevents it from executing
that one last time.

Thanks for your help, Nick!
