;;; Patch file for ZWEI version 128.2
;;; Reason:
;;;  Kill-Or-Save-Buffers improvements:
;;;  
;;;   1. Expanded window size (now takes up most of the screen for easier
;;;  viewing) -saz
;;;  
;;;   2. COMPILE option offered for any LISP syntax buffer. -keith
;;;  
;;;   3. Takes numeric arg (16, or Control-U Control-U), means initially mark
;;;  all buffers to be killed. -saz
;;;  
;;;   4. Display dots (. . .) so user can follow line from pathname to check
;;;  boxes. -keith+saz
;;; Written 14-Nov-88 16:18:07 by keith at site Gigamos Cambridge
;;; while running on Tonic from band 4
;;; with Experimental System 130.4, Experimental ZWEI 128.1, Experimental ZMail 75.0, Experimental Local-File 77.0, Experimental File-Server 26.0, Experimental Unix-Interface 16.0, Experimental Tape 27.0, Experimental Lambda-Diag 19.0, Microcode 1762, SDU Boot Tape 3.14, SDU ROM 102, 11/11.
