Add option to remove "Delete" button from node edit form and move it to node local tasks

The title says the whole thing. :-)
Actual code for this action is quite simple like this (taken from http://drupal.org/project/mini):

/**
 * Implementation of hook_menu_alter().
 */
function mymodule_menu_alter(&$callbacks) {

  // Move "Delete" button to local tasks instead of node edit form
  if (isset($callbacks['node/%node/delete'])) {
    $callbacks['node/%node/delete']['type'] = MENU_LOCAL_TASK;
    $callbacks['node/%node/delete']['weight'] = 2; // make sure it is after Edit
  }
}

/**
 * Implementation of hook_form_alter().
 */
function mymodule_form_alter(&$form, $form_state, $form_id) {

  // Move "Delete" button to local tasks instead of node edit form
  if (empty($form_state['submitted'])) {
    if (strcmp(substr($form_id, -10), '_node_form') == 0) {
      unset($form['buttons']['delete']);
    }
  }
}
