Actually, is scrub_nondigest is Yes, bin/arch --wipe will work but there
are lots of caveats. In this case, bin/arch --wipe will just not remove
the 'attachments' directory. The issue is if scrub_nondigest was always
Yes for this list, that's the right thing to do, but it it was No at
some time in the past and changed to Yes, there are already two copies
of each attachment from the No period (one scrubbed from the archive and
one from the plain digest) and running bin/arch --wip will leave those
and create  third copies from the attachments in the mbox.

The more serious issue is if scrub_nondigest was Yes at some time in the
past and is now No, bin/arch --wipe will lose the attachments from the
Yes period.

In any case, for attachments scrubbed by scrub_nondigest, there are
links to them in the message bodies in the mbox and the list names in
those links will now be wrong, and bin/arch won't (can't) fix them.

This is why I chose in my script to kick the issue back to the user.

That much seems good, but as I note above it's a bit more complicated if
the scrub_nondigest setting has changed over time.

OK
