Misplaced MIME headers

[Karl Kleinpaste <karl@charcoal.com>]

Using this evening's CVS, if I write a piece of mail containing this
content...

	--------------------------------
	General test text.

	[#mml type=text/plain disposition=attachment]
	Attachment text containing "type=text/plain disposition=attachment".
	[#/mml]
	--------------------------------

...then the resulting message actually sent contains MIME parts where
the MIME headers of the 2nd part are misplaced in the body, rather
than in the part's header:

	--------------------------------
	--=-=-=

	General test text.


	--=-=-=
	Content-Disposition: attachment

	Attachment text containing "type=text/plain disposition=attachment".
	MIME-Version: 1.0
	Content-Type: text/plain; charset=us-ascii

	--=-=-=--
