Integration with pageroute module

I needed to have the user's form exposed to pageroute, and it was relatively easy to do with this add-on right at the end of the module. (It can probably be roped off in a *.inc too, if desired.)

/**
 * Pageroute integration
 */

/*
 * Implementation of hook_form() and hook_form_submit() as wrapper functions
 * TO DO: implement hook_form_validate() too
 */
function user_mailman_register_form($account=false) {
  $form = _user_mailman_register_form($account);
  $form['user_mailman_register']['uid'] = array(
    '#type' => 'value',
    '#value' => $account->uid,
  );
  return $form;
}

function user_mailman_register_form_submit($form_id, $form_values) {
  $account = user_load(array('uid' => $form_values['uid']));
  _user_mailman_register_subscribe($account, $form_values);
}

/*
 * Implementation of hook_pageroute_info().
 */
function user_mailman_register_pageroute_info() {
  return array(
    'form_view' => array('name' => t('User Mailman Registrations'), 'base' => 'user_mailman_register', 'default_target' => PAGEROUTE_FORWARD),
  );
}

/*
 * Implementation of pageroutes' hook_page()
 */
function user_mailman_register_page_form_view($route, $page, $form) {
  $account = user_load(array('uid' => pageroute_page_get_uid($page, 'access user_mailman_register')));
  $form['page_form'] = array(
    '#type' => 'subform',
    '#id' => 'user_mailman_register_form',
    '#arguments' => array($account),
    '#data_separation' => FALSE,
  );
  return $form;
}
