 wp-includes\kses.php, there is:

 {{{
 function wp_kses_split( $string, $allowed_html, $allowed_protocols ) {
         global $pass_allowed_html, $pass_allowed_protocols;
         $pass_allowed_html = $allowed_html;
         $pass_allowed_protocols = $allowed_protocols;
         return preg_replace_callback(
 '%(<!--.*?(-->|$))|(<[^>]*(>|$)|>)%', '_wp_kses_split_callback', $string
 );
 }
 }}}


 before the return, there are variables, which are not used anywhere inside
 that function, is that correct?
