From 6cec169a54d790b4a898d1c33803e749db657248 Mon Sep 17 00:00:00 2001
From: "Richard M. Stallman" <rms@gnu.org>
Date: Thu, 5 Feb 1998 03:31:41 +0000
Subject: [PATCH] (Fdescribe_bindings_internal): Renamed from
 Fdescribe_bindings.  New arg NOMENU. (syms_of_keymap): Corresponding changes.
 (describe_buffer_bindings): Get NOMENU out of the arg list. Pass it along to
 describe_map_tree. Improve text of `alternate_heading'.
