 The `login_header()` function's third parameter is optional and accepts a
 `WP_Error` instance. The default value, though is a string, which is
 missing from the inline documentation.

 To prevent someone from passing a string (which would not be added to a
 new `WP_Error`), `if ( empty( $wp_error ) ) {}` could be changed to `if (
 ! is_wp_error( $wp_error ) ) {}`.
