David wondered in id:87y58xv71x.fsf@zancas.localnet what filtering
is done by CLI and what by lib.

But where should the "problem" presented in the Subject: header should
be handled. I did some hacks to emacs client to drop the ^J (newline)
characters from Subject: and From: headers but should these be filtered
in CLI (or in lib) instead?
