Or either 1) use only the BSD "ls" or 2) if you have a sufficiently
modern version of S5, use "ls" only with the "-q" or "-b" options, so
that non-printable characters are displayed as "?" or as "\nnn".
Of course, this doesn't cover all the programs that can be coaxed into
printing out evil file names....
