[Peter Bloomfield <PeterB src gnome org>]

commit a8fbda3bf3a2d5ed8f687b0ccfb7a74ce41966ac
Author: Peter Bloomfield <PeterBloomfield bellsouth net>
Date:   Fri Apr 20 09:20:33 2012 -0400

    Hide current message sooner instead of later
    
    	* src/main-window.c: hide current message immediately, instead
    	of in the idle callback; use gdk_threads_add_idle convenience
    	function.
    	* src/balsa-message.c (balsa_message_set): message is already
    	hidden.
