Works better without this..  Remove this as it isn't needed,
and makes you enter something like 1<CR>2<CR> to get it to like the 1...

    And then combine the two onto a single line... This will give you
91 chars...

  This of course allows the 1 Char answer: "M", where you use
  -DM="main......."
