From 86f281250c79bd9bb9fb8e89a273969a767e2292 Mon Sep 17 00:00:00 2001
From: "Richard M. Stallman" <rms@gnu.org>
Date: Tue, 14 Jul 1998 23:42:21 +0000
Subject: [PATCH] (find-function-regexp): Added :version 20.3.
 (find-variable-regexp, find-function-after-hook): Likewise.
 (find-function-recenter-line): Likewise. (find-function-recenter-line):
 Remove autoload cookie. (find-function-do-it): Made more solid. 
 `save-excursion' around call to `find-function-noselect'. 
 `find-function-other-window' and `find-function-other-frame' point behaviour
 should be correct now when function in a current buffer.
 (find-function-setup-keys): New function to set up keybindings.
