[drupal-devel] unlimited comments displayed on drupal.org is a hack?

Hi, The stock Drupal only allows setting of comment displays between 10 and 90. Drupal.org clearly has something which makes all comments display. The 'makeover node' for example has 155 comments, all displayed: http://drupal.org/node/11695 Is this some hack in the drupal.org code, or have I seriously missed some setting? It would probably be diserably to provide such a setting on the comment control panel wouldn't it? Goba
