upload.php and admin_url

in upload.php there are lines:

——————————————
$returnurl = get_bloginfo(“wpurl”) . “/wp-admin/post.php?post={$_POST[“ID”]}&action=edit&message=1″;

should be

$returnurl = admin_url( ‘post.php?post=’ . $_POST[“ID”] . ‘&action=edit&message=1’ );

——————————————
$returnurl = get_bloginfo(“wpurl”) . “/wp-admin/upload.php”;

should be

$returnurl = admin_url( ‘upload.php’ );

Thx
