Ditch the wNAF modification

This is another micro optimization that introduces needless complications
for the sake of saving a few cycles. Specifically, by ditching the rule
defining the wNAF representation (at most one of w+1 consecutive digits
is non-zero) for the topmost digits, one can sometimes save a few digits
at the cost of crazy loop conditions and other weirdness. That's not worth
it.
