<sigh> pagebreak implementation is still flawed here, the used
range is used to determine whether the page break should be
considered ( or not ) Problem is that it is not the used
range but rather the rightmost column position that contains content
( but not necessarily the column that contains content but rather
the righmost column that has content ( or even that is covered either
by spillover from an adjacent column or drawing )
