        to show that a given list is to be in the simple list tabpage.
        This has now nothing to do with the actual number of list level a
        list has, only how many will be shown in the user interface.

        i.e. create a simple list in 2000 and open it in 97 and 97 will
        claim (correctly) that it is an outline list. We can set our
