 When a query var and the query_var of non-public CPT are the same:
 * You will get a 404 error even when the permalink exists.
 * redirect_guess_404_permalink() returns the permalink of '''other''' post
 which has slug like {query value}%.

 Here an example:
 * CPT `foo` has `'public' => false`.
 * The permalink `/a123` exists.
 * The permalink `/bar/456` exists.
 When you visit `/a123?foo=4`, You will redirect to '''other''' url
 `bar/456?foo=4` and get a 404 error.
 I want to get `/a123` page and $_GET[ 'foo' ] which is not the CTP
 `query_var`.

 I think CTP `query_var` parameter must be set to false, if `public`
 parameter is false.
