From f3b330d6d810be33ddf73e1b5375b602e086497b Mon Sep 17 00:00:00 2001
From: Karl Heuer <kwzh@gnu.org>
Date: Tue, 30 Sep 1997 07:36:28 +0000
Subject: [PATCH] (finder-mode-map): Bind [mouse-2]. (finder-compile-keywords):
 Match compressed file names, but don't put compression extension in the
 output. (finder-find-library): Deleted. (finder-commentary): Use
 locate-library, not finder-find-library. (finder-mouse-select): New function.
 (finder-summary): Mention mouse binding. (finder-exit): Kill "*Finder
 Category*" buffer too.  Avoid error from deleting sole window.
