From ac3eb4395c6215737b4c4bf99b1b186ecdfbf07c Mon Sep 17 00:00:00 2001

Subject: [PATCH] Eliminate gratuitous calls from MARK-FLASH and SIT-FOR to
 KEYBOARD-PEEK-NO-CHAR.  These calls were originally there to eliminate
 unnecessary screen update and to make the cursor flash appropriately; recent
 changes to KEYBOARD-PEEK-NO-CHAR make this undesirable.
