On my platform (SunOS 5.7/Solaris 7) there are no grep options that force
both the file name and matched text to be printed.  The /dev/null trick is
necessary when you specify a pattern that globs to a single file.

To run a pipe line via `M-x grep', just do this:

        (setq null-device nil)

Should that trick be documented somewhere?
