Some missed translations texts

Hi,
I found there's some texts that can't be translated on tableofcontents.admin.inc. Line 452 should be:

if ($toc_automatic == 99) {
	    $options = array(
	    0 => t('No table of contents'),
	    1 => t('Add the table at the top'),
	    2 => t('Add the table at the bottom'),
);

Regards,
