----------------------------------------------------------------

On another aspect, why the PFOR/FOR is encoding the number of compressed 
integers into the block header since this information is already stored in the 
stream header (block size information written in 
FixedIntBlockIndexOutput#init()). Is there a particular use case for that ? Is 
it for the special case when a block is complete (when the block encodes the 
reamaining integer of the list) ?
