        ** See #57583.

        * message-list.c (build_tree): save/restore the selection when we
        update.
        (message_list_set_selected): util to set the selected messages
        from a list of uids.
        (build_flat): same.  I wonder if etree's unbroken enough to use it
        more directly?
