I understood, I'm just astonished that the current behavior is
considered a bug, since it seems so useful.  Is there a
compelling reason not to allow dired-get-marked-files to
return nil when no files are explicitly marked, when it's
given a special distinguished value for ARG?  It's a
pattern that's used in many other places.
