Auto detected external link (ie. without barket [ and ]) are appearing as http:www.google.fr in place of

A user have posted in french forum
http://forum.dokuwiki.org/post/26620 that the problem is in /inc/parser/xhtml.php file.
The code
// url might be an attack vector, only allow registered protocols
if(is_null($this->schemes)) $this->schemes = getSchemes();
list($scheme) = explode('://',$url);
$scheme = strtolower($scheme);
>>>> if(!in_array($scheme,$this->schemes)) $url = '';
Must be modified as :
if(in_array($scheme,$this->schemes)) $url = '';
Suppress the "!".
