When I did ctl-x ctl-f DOYLE;.LISPM (INIT), ZWEI created a buffer called .LISPM (INIT) containing the file DOYLE;.LISPM >. Thus, when I did ctl-x ctl-s, it wrote out the file as DOYLE;.LISPM 1. Also, somehow, when I did ctl-x ctl-f twice, it created two such buffers, with the same name and same (misnamed) file contents.
