I am analyzing the authentication system wordpress, caught my atension the function logic wp_authenticate_cookie in (wp-includes/user.php) and decided to make a very small change.

I made a file of changes:

Thanks for the patch fitorec, but we don't refactor code for the sake of refactoring. Please see ​http://make.wordpress.org/core/2011/03/23/code-refactoring/

Sorry you've not received a response until now.

While a future commit in this file will surely clean up the all-on-one-line if statement, we prefer returning early from functions whenever possible. The patch here would change that and make it less clear what happens when the function receives a WP_User.
