Fixed my not-quite-right logic so that we don't accidently set the body

2000-10-27  Jeffrey Stedfast  <fejj@helixcode.com>

	* e-msg-composer.c (e_msg_composer_new_with_message): Fixed my
	not-quite-right logic so that we don't accidently set the body
	contents using a plain text attachment instead of the actual body
	of the message :-)
