  ZWEI CAN GET CONFUSED AS TO WHAT FILE TO WRITE TO WHEN YOU
DO A C-X C-S.  NAMELY, GENERATE ONE ZWEI WINDOW WITH THE MOUSE,
READ IN A FILE, GENERATE ANOTHER AND READ IN A FILE, AND RETURN
TO THE FIRST.  IF YOU CHANGE IT AND TRY TO WRITE IT OUT THE
FIRST BUFFER, IT INSTEAD WRITES OUT THE SECOND BUFFER.
  ANOTHER TIME (I M NOT SURE EXACTLY WHAT I DID) IT MANAGED TO
WRITE A BUFFER BACK UNDER THE FILE NAME BELONGING TO ANOTHER 
BUFFER.  IN THIS PROCESS, THE BUFFER WRITTEN WAS RENAMED SO
BOTH BUFFERS WOUND UP WITH THE SAME NAME.
