Use !is_user_logged_in instead of !$user->ID

[Eteq]

The subject line pretty much says all. I'm kind of integrating a user system of my own to allow comments into wordpress posts as if logged in amongst other few minor changes like session sharing. I've managed to do so as a plugin, until I got stuck with this.

The fact that many places in the wordpress code checks for the user id, instead of using the is_user_looged_in renders the purpose of that function useless for plugins.

I'll volunteer to patch this one up unless Eteq or someone else wants to.

Any examples? I've found only one instance in wp-includes/capabilities.php:

if ( ! $user || ! $user->ID )
	return false;

there's a patch for that
