	Hmm..  Apparently I do some bad assumptions at
	transports/mimeheaders.c: mime_received_convert()
	function.

	I think it was written before I went and did proper Received:
	header folding in the router -- that is, while that header was
	single line, and it contains assumptions of that effect..

	It must be modified to throw in header folding detection,
	and some actions of same sort.
