Request-for-sanity:

The list of ~ commands in compose-mode is getting longer and longer.
As a complexity reducing feature, how about adding a send-message-hook
variable, such that when it is set to a mush command, that command
is executed after telling mush to send the message and before the
message is handed off to the MTA.  Thus, the hook could be set to a
shell script to add a signature or a fortune as desired.  Then, a user
wishing the (less-then-useful) fortune feature could map! ~F to a command
to set the hook variable, ala the way I add R-R-T: headers:

	# msg-comp-mode
	map! +rr "\n~:my_hdr Return-Receipt-to: loverso@Xylogics.COM\n"
	map! -rr "\n~:un_hdr Return-Receipt-to:\n"

The ~ commands t s c b h don't have any effect when edit_hdrs is set.
I assume this is because of the implementation of edit_hdrs; it would
be nice to either fix this implementation pitfall or not list those
items in ~? when edit_hdrs is set.

A last nit is that ~H doesn't get me any ignored headers; it would be
nice if there was a way around that.

(My real problem is that I always think "~F" is a "~f" that gets me
ignored headers, and then I add this junk fortune to a letter.  Mush
doesn't indicate its adding the fortune until its too late to stop it.
I don't really use ~S; whenever I want a signature, I just `:r ~/.sig'
in vi; I used to use ~$s (its got my sig in it, too) before edit_hdrs.)
