I replaced that SfxPoolItem* in SearchAttrInfo with
a much safer SfxPoolItemHolder and adapted and
simplified used code - it does not need to take
care of Item lifetime/Cloning itself. That works
well.
I did not find out why that 'invalid' state is used
in the SrchAttrInfoList, but seems to be needed.
Thus I keep this for now as it is (it can be all
expressed/used using SfxPoolItemHolder, too).
