I fixed them, but i disagree on the correctness of natural=land. The  
multipolygon relation already unambiguously says that the "holes" are land  
if there's no other tags sayng that it's eg. wood etc.

Also if the lake-within-island doesn't itself have islands, it doesn't  
need to be a multipolygon, as it is residing in the "hole" (island) of the  
larger lake.
