  * Don't include the massive list of --with-prog --prog-args flags in help text
  Instead have just two generic ones in the help text and at the bottom,
  list the programs that the flags apply to.
  This still needs to be properly word wrapped to fit in 80 cols (as does the
  rest of the help text).
