    wc: Removing output padding
    
    Since the first column is not padded on the left, all the others will
    not be aligned, so the padding isn't very useful.
    
    POSIX says thet output should have the form
    
      "%d %d %d %s\n", <newlines>, <words>, <bytes>, <file>
    
    so just do that.
