Jeffrey Stedfast f53bad6e04 Don't display an unread icon for a parent message status if it has unread 
2003-06-16  Jeffrey Stedfast  <fejj@ximian.com>

	* message-list.c (ml_tree_value_at): Don't display an unread icon
	for a parent message status if it has unread children but has been
	read itself. Instead, show that we have unread children by just
	making the message test bold (which it was already doing, so
	yay... this was easy). Fixes bug #42630.
