The doc for node_example_form at
http://drupaldocs.org/api/head/function/node_example_form contains an
example taken from
contributions/docs/developer/examples/node_example.module which no
longer provides proper display:


The code goes:

<?php
function node_example_form(&$node) {
  $form['title'] = array('#type' => 'textfield', '#title' =>
t('Title'),
// [...]
  return array_merge($form, filter_form($node->format));
}
?>




which causes the Forms API to display the input filter form on its own,
without a visual container (fieldset).


Is should rather be:

<?php
function node_example_form(&$node) {
  $form['title'] = array('#type' => 'textfield', '#title' =>
t('Title'),
// [...]
  $form['format'] = filter_form($node->format);
  return $form;
}
?>




If the doc is generated from code, the change should also be applied to
contributions/docs/developer/examples/node_example.module.


(fix suggested by Morbus).
