Adding Googlebot to HidePostgoogl

There is this code in hidepost but it isn’t working. I believe the user-agent is wrong. IIRC, the user agent of googlebot should be Googlebot/2.1 or something.

How do i add it in?

$hidepost_allow_bot = get_option('hidepost_allow_bot');
	if ($hidepost_allow_bot == 1) {
		$useragent = $_SERVER['HTTP_USER_AGENT'];
		if (stristr('google Googlebot googlebot Googlebot* Googlebot/2.1 msnbot ia_archiver lycos jeeves scooter fast-webcrawler slurp@inktomi turnitinbot technorati yahoo findexa findlinks gaisbo zyborg surveybot bloglines blogsearch pubsub syndic8 userland  gigabot become.com', $useragent) !== false) {
				return $matches[2][$m_id];
			}
