OTOH, the pre-mbox Rmail was always expanding the headers in
rmail-edit.  So I think we will be OK having header editing working
first, even if full headers are deemed slightly inconvenient by some
users.  (FWIW, I don't mind the expanded headers at all, and I do use
rmail-edit quite a lot.)  It is more important, IMO, to have Rmail
working at least as well as it was before the mbox merge than to
improve it.  We can always improve it later.
