Check result of presave before showing message

I need to validate unpublished status in hook_node_presave.

If my hook prevents node from been unpublished, the status message does not correspond to the actual status of the node.
My patch is:

function publishcontent_toggle_status($node) {
  // XOR the current status with 1 to get the opposite value.
  $node->status = $node->status ^ 1;

  /** SAVE THE INITIAL VALUE STATUS */
  $trytoset = $node->status;

  // If this content type specifies that a new revision should be created on
  // editing, then make sure to respect this option.
  $node_options = variable_get('node_options_' . $node->type, array());


  if (in_array('revision', $node_options)) {
    $node->revision = 1;
  }
  node_save($node);

  /** CHECK STATUS  */
  if ($trytoset==$node->status)	
  	drupal_set_message(_publishcontent_get_message($node->nid, $node->title, $node->status));
  drupal_goto($_SERVER['HTTP_REFERER']);
}
