The -t flag (thanks for that, btw !) allows to not fusion the buffers, 
but it still respects topology, i.e. no overlaps allowed in polygons. 
The parts where buffers overlap are separate polygons from the rest of 
the buffer, and they have more than one category (similar to the result 
of importing a shapefile with overlapping polygons).
