From 937943b4502499a9afae32313f47a73352a21a41 Mon Sep 17 00:00:00 2001
From: Pascal Rigaux <pixel@mandriva.com>
Date: Fri, 5 Jan 2001 17:12:51 +0000
Subject: move to new ask_from's: - ask_from_entries_ref is deprecated, use
 ask_from_entries_refH - ask_from_list now calls ask_from_entries_refH_powered

still not done:
- ask_from_treelist should use ask_from_entries_refH_powered,
and lists with no help should use CList (List is bad)
- keyboard and mouse binding is still rough
- enhance the look
