Seems like that rather than add more complexity to mtree, the answer
here is just to use a different mtree spec file.

That is, something like

  grep whatever original-spec-file [ | grep otherstuff ]... >/tmp/temp-spec
  mtree -f /tmp/temp-spec

If a change/addition to mtree is desirable, IMO, it would be to
allow "-f -" so the temp file isn't needed (just read spec from stdin).
