redundant </div> messes theme

There is an extra redundant </div> at the end of line 274 that should be extracted.

Instead of:

$form['tellafriend_message'] = array('#value' => filter_xss_admin("<strong>Message to be sent:</strong><br />" . nl2br(t(variable_get('tellafriend_message', 'You are invited to check out !sitename at !sitelink'), $placeholder_values)) . '<br></div>'));

should be:

$form['tellafriend_message'] = array('#value' => filter_xss_admin("<strong>Message to be sent:</strong><br />" . nl2br(t(variable_get('tellafriend_message', 'You are invited to check out !sitename at !sitelink'), $placeholder_values)) . '<br/>'));

And one extra tiny thing: at line 219, it should be "the word" instead of "the world"...
