From 8028133c79b781265cbcce0b6a9fce5b884c817b Mon Sep 17 00:00:00 2001
From: Jason Wilson <edu/mit/csail/zurich/jawilson>
Date: Thu, 19 Aug 1993 05:56:15 +0000
Subject: [PATCH] Rewrote the loop in KEYBOARD-MACRO-EXECUTE so that
 CALL-WITH-CURRENT-CONTINUATION would get called just once per keyboard macro.
  I also made the call to COMMAND-READER supply an optional arguement (#f)
 that wasn't being supplied before.
