From 6f4c6ed99007f89099b74bfbb95f5ca58b0ead3c Mon Sep 17 00:00:00 2001

Subject: Straighten out voicing of yesno dialogs. Make it so
 gui_syncyesno_run() does not modify the text_messages passed as argument,
 simplify the code and even reduce size a bit. The key is to support voicing
 at the level of the text_message itself.
