Last pass change incorrectly set when admin user saves user edit form

Any time a user with administer users perms saves another user edit form, the last password change is updated with the current time. Additionally, the user is reported to have been forces to change his pass.

The following code from the hook_user implementation shold only run if the $edit['pass'] is not empty. And maybe it should only run if the user himself changes it.

		case 'update':
			if($edit['pass'] != $account->pass)
			{
				db_query
				(
					'UPDATE {force_password_change_users} SET last_password_change = %d WHERE uid = %d',
					time(),
					$account->uid
				);
			}

I'm also seeing a related bug where I can't force an individual user to change her pass even though I set it to be forced on her user page. I will create another issue when I figure that one out.
