        their own tab page to themselves one of the reserved bits is used
        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
        continuous flag in these lists to store this information.
