It didn't work. Batch deliveries to files (and pipes) only worked when
the file or pipe command was specified on the transport, not in a
redirect router.

However, the good news is that I decided this was anomalous, so I have
made it work, at least in the straightforward cases I have tested. The
code is committed to the CVS so will be in tonight's snapshot.
