From 8f90f5941618e606b4de55c84b6a8c0c534e7aa5 Mon Sep 17 00:00:00 2001
From: "Richard M. Stallman" <rms@gnu.org>
Date: Sat, 6 Mar 1993 06:15:05 +0000
Subject: [PATCH] (isearch-unread): Handle multiple args. For Emacs 19, use
 listify-key-sequence. If not Emacs 19, assume they are a meta sequence.
 (isearch-other-meta-char): Pass the whole key sequence.
 (isearch-other-control-char): Make this alias for ...-meta-char.
