	* e-msg-composer.c: add ask argment.
	(autosave_manager_query_load_orphans): move the load loop out of
	the dir reading loop.
	(autosave_manager_new): move initialization out or register.
	(autosave_manager_register): protect against recursion with ask.
	(init): call new, this still needs to be moved.
