I like it better, too, but we still need the "range += rangesz" part,
so I don't think it will work.  I suppose that could be moved to the
update expression of the "for" loop.  Or, since we don't use "i" in
the loop at all, maybe we could do something like this:

    for (; range < rend; range += rangesz)
