Unused $pwd variable in wp_login() function

[epper]

I was looking the code of wp_login() in wp-includes/pluggable.php and I've seen that there's an unused variable: $pwd on line 305:

303 	        } else {
304 	            $error = __('<strong>ERROR</strong>: Incorrect password.');
305 	            $pwd = '';
306 	            return false;
307 	        }

Perhaps #2244 should be decided upon too, I think i removed that variable in the patch there too.
