That could work.  It's easy to filter out all Content-ID:
lines.  But if I wanted to keep forwarded messages perfectly
intact, it's not as simple.  It usually doesn't matter, but
some recipients might want to see _all_ original header lines
in forwarded messages.

The changes to nmh are trivial, see below.  I'm not fond of
adding options.  But I think it might be easier than deciding
whether we should just eliminate Content-ID: completely :-)
