do_action('login_footer') missing in wp_login.php 3.1-beta2

Code base:

Wordpress 3.1 Beta 2, file wp_login.php.

Problem:

On $action='login', no callback is made to do_action('login_footer').

Discussion:

For any action except login, a new local function login_footer() is called at the end to close the page by outputting </body>, </html> etc.

However, for the login action, this function is not called, and the older 3.0 code still terminates the page.

Workaroud:

In file wp_login.php, before line 137 (i.e. before the </body> tag), insert:

<?php do_action('login_footer'); ?>

Solution:

The end of the login action needs to be made compatible with the function login_footer().
