Whoops, it's a widget, so it's in the widget directory.
PHP Code:
$allow_html = ((vB::$vbulletin->forumcache[$post['forumid']]['options'] & $optionval) AND $this->config['allow_html'] ? 1 : 0);
$post['previewtext'] = fetch_censored_text($parser->get_preview($post['pagetext'], $this->default_previewlen, $allow_html));
$post['pagetext'] = fetch_censored_text($parser->do_parse($post['pagetext'], $allow_html));
