 Setting a query var to NULL will convert it into an empty string:

 {{{
 $name = 'test';
 $value = NULL;
 set_query_var($name, $value);
 $get = get_query_var($name);
 echo $value === $get ? 'same' : 'different';
 var_dump($get);
 }}}

 This will output "different" and showing that the query var now is an
 empty string.
