I looked again at the pfgw doc on newpgen formats. I was correct. When the base != 2, then newpgen sieves per my suspicion. I will modify sgsieve to support a switch for "true" SG sieving (what it does now) or "generalized" SG sieving (which is what newpgen does). Since nobody (as far as I know) is searching for Sophie-Germain primes for base != 2, this shouldn't be a problem.

Note this is one of the reasons I dislike newpgen file formats. ABC and ABCD formats are easier to understand.
