Yeah, it was used in some preliminary versions of the code while I was
developing the new algorithm, but there were lots of changes between
when I started working on merge-ort and when it was finally ready to
submit for review.  I must have just overlooked that this parameter
was no longer needed.  Thanks for catching and cleaning up.

Yep, makes sense.
