Actually ... yes.  At least some of the complainers are on this list!

(And that's not the only message regarding that).

Hm.

This actually suggests to me that having this done in the format engine
is wrong, and the RIGHT place to do it is inside of mhbuild, which is
the tool that converts a draft file (which doesn't technically have to
be in RFC 5322 format) into a valid RFC 5322 message, and we should do
that for a number of headers.  I suspect that might be too much for 1.7,
though.  Due to liberal use of %(formataddr), we're mostly fine for
address headers.

Would people be happy with that?
