send a message as a message/rfc822 attachment instead of inserting it into
the body of a new message

* alias tagging

allow the user to tag aliases when invoking the alias-menu from send-menu

* PGP support needs some work in the area of getting the keys to use for

uniqueness

* add secondary sorting support
	sort <primary-method> [ <secondary-method> ]

	mutt -s "here is the data" -a ~/project/run2.dat boss

* group-reply to tagged messages should include all recipients

* <tab> should bring up the alias-menu when entering an address

* the url-menu should allow the user to view more than one url before
exiting.

* allow reverse-* sorting with the `threads' option

* allow query of boolean variables with the set command:
	set ?askcc => "askcc is set" or "askcc is unset"

* trim the size of the References: field to ``N'' message-ids when sending
mail
