  OPPS! (Red faced) You are right - I did mean "w" and not "r".

 I recommended the r filename approach so that the file *WOULD* be written
 under a new (different) name, then exiting using the q! option would leave
 the original file untouched and the edited file under the new name.
 (Similar to what ZZ does by saving the unedited original as filename.bak)
