The dot kernel should return 0 for N=0. An existing early bail checks for N<0 and returns 0 in this case. Adjust this to N<1 to simplify maintenance: with this change we don't have to reason through subsequent code to confirm it handles that corner case correctly, and future platform ports have a slightly more pleasant baseline to begin from.
