    Update README in regard to ls(1)
    
    I marked out -m, -s and -x, because they are either visual flags
    for interactive mode, which are better solved with tools made for this
    job, or superfluous in another sense.
    For example, -s basically "steals" the job from du.
    In general, some of these options might still be easy to implement.
    The options -S and -f are important though, as they are sorting-options
    with real use.
