    # elements are by definition equivalent to '.', however field splitting

    #     at the beginning and at the end,
    #   - GNU bash, /bin/sh on AIX and HP-UX, and /bin/ksh on AIX, HP-UX,
    #     Solaris lose empty fields at the end.
    # The 'case' statement is an optimization, to avoid evaluating the
