  * Save horazontal space in the --help output by omitting options to short flags
  So instead of "-f FLAGS --flags=FLAGS" we get just "-f --flags=FLAGS"
  This makes rather better use of 80 cols and means the flag descriptsion
  are not squeesed into such a narrow column.

    M ./Distribution/GetOpt.hs -2 +2
    M ./Distribution/Simple/Command.hs -1 +4
