> Its pretty common that positionIncrement can overflow, this happens really easily 
> if people write analyzers that don't clearAttributes().
> It used to be the case that if this happened (and perhaps still is in 3.x, i didnt check),
> that IW would throw an exception.
> But i couldnt find the code checking this, I wrote a test and it makes a corrumpt index...
