Node revision view page does not show that revision

Node revisions don't work. That is not an exaggeration. Try this simple test under a HEAD installation: create a node with the "create new revision" checkbox checked. Then edit it, with the "create new revision" checkbox checked. Then, go to the revisions page and try to view the old revision. It doesn't work: instead, the new revision is displayed. This is a critical error as Drupal 6 cannot be released with node revisions in this state.

I have double checked this on a clean HEAD install, same thing happens.

I believe the error is in this line:

<?php
$items['node/%node/revisions/%/view'] = array(
    'title' => 'Revisions',
    'page callback' => 'node_show',
    'page arguments' => array(1, NULL, TRUE),
    'type' => MENU_CALLBACK,
  );
?>

It should be something like:

<?php
$items['node/%node/revisions/%/view'] = array(
    'title' => 'Revisions',
    'load arguments' => array(3),
    'page callback' => 'node_show',
    'page arguments' => array(1, NULL, TRUE),
    'type' => MENU_CALLBACK,
  );
?>

However, I'm hardly an expert at the menu system, so this could turn out to be completely the wrong solution. In any case, however, something is going wrong in the loading of the older revision of the node. Whatever the cause, this certainly needs to be fixed.
