If we are doing Reply-to-All, do not include any of the user's email

2002-06-10  Jeffrey Stedfast  <fejj@ximian.com>

	* mail-callbacks.c (mail_generate_reply): If we are doing
	Reply-to-All, do not include any of the user's email accounts in
	the To: field. If, after this, the To: field is empty - then
	promote the first recipient in the Cc: list to the To: field.
