OK

I have look at the code where GetDataArea is called. The only places 
where a behaviour change could happen are in function GetDBData ( 
sc/source/ui/docshell/docsh5.cxx )
if bOnlyDown is true. In this case, the area will be shrink - if needed 
-  only for the number of rows. Before, all 4 sides (top, right, left 
and bottom) could be shrink. But this change exists only if we shrink. 
For expanding, the behaviour was already ensured as described (bOnlyDown 
= true would have expanded only down, not the other directions).

This now makes the behaviour symmetric between shrinking / expanding the 
area. Based on flags and description, the former behaviour was buggy, 
but maybe something has been build depending of it. Despite knowing what 
is changed, I was not able to produce a way of using it that seemed to 
be problematic. I see you have worked on this function, maybe something 
will strike you immediately :- ).

So here the patch. If no one object, I will push it during my Christmas 
Holiday.

Best regards
