tokens in html not transformed

I noticed the subcription link in the confirmation message was not transformed in the html message. The link in plain text did work.
It seems this issue has occured earlier (http://forum.civicrm.org/index.php/topic,25187.0.html), but to me it was new after the upgrade to 4.3.
I removed the space in line 158
return preg_match("/(^|[^\{]) $token/", $str);
> return preg_match("/(^|[^\{])$token/", $str);
and it works now.
