So I tried adding a "(nil)" in the custom agenda section. If this were
allowed (presumably ignored), I could write a function that returns nil
unless there were items tagged REFILE, in which case it would return

  (tags "REFILE" ((org-agenda-overriding-header "REFILE")))

But having (nil) caused an error. I guess I could make the entire "My
Custom Agenda" section be the output of a function, but that seems overly
complex.

  -k.
