I didn't look at the patches very much, but I like the idea, a lot. This
is the way it should be.

Might be useful, but can be added later on.

The same for better handling of mail-followup-to: and reply-to:. For
those, I'm not sure if a keybinding for "widening" the recipients is the
right choice, as they both mean *changing*, not necessarily widening the
recipient list. Maybe you can come up with an approach here that extends
well to those too later on. ;)
