My Makefile didn't set the envelope sender when it auto-sent the diff to the
list, so it was rejected as not being from a list member.  I forgot to edit
the subject when I manually forwarded it back to the list, after trimming out
the rest of the bounce message.  I updated my Makefile so it should work okay
next time.

I put it in here for consistency with the PUT command -- and I put it in there
because I wanted to make sure that the client and server were still in sync.

It was/is supposed to catch the case where a client improperly calculated the
size of the message based on CRLF line endings, then sent it to the server
with the proper LF-only endings.  If "finished" CR LF isn't the next thing
sent, the server can detect that, rather than padding the message out to the
specified length with whatever the client happened to send next.
