Thanks for this patch.

It's not clear there's a real benefit to using Szu-Wei Lee's algorithm 
for short blocks. It only saves one multiplication per window, and adds 
additional complexity. I wasn't able to observe any performance 
improvement.

If you found otherwise, I'd be interested in your analysis.
