 The following line in formatting.php throws a notice-leve error
 (Uninitialized String Offset) if '$curl' is an empty string:

 29:              if (isset($curl{0}) && '<' != $curl{0} && $next) { // If
 it's not a tag

 Clearly, isset($curl{0}) is intended to prevent empty strings from being
 tested, but isset doesn't check string offsets.

 Changing to the following prevents empty strings from being considered:

                 if ($curl && '<' != $curl{0} && $next) { // If it's not a
 tag
