Since we're on the subject, is there a way to make Emacs not add "/dev/null" 
(UNIX, or "NUL" on Windows) at the end?  I have a couple of "specialized" 
grep-like commands that I run as the command in M-x grep, and I've adjusted 
those scripts to ignore a trailing "/dev/null" argument in order to be 
compatible with Emacs.  (I would never add "/dev/null" interactively if I were 
invoking them.)

Thanks!
