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!
Mark Ludwig
