Why not have Emacs try "ls -l --dired" first, and, if that doesn't
work, fall back on "ls -l" without --dired?  The --dired usage would
be considered to "work" only if the output ended in the required
//DIRED// and //DIRED-OPTIONS// lines in the proper forms.

This procedure should be reliable in practice.
