biondizzle b50968dfaf FIX: acc_scale was double-multiplying by scale_log2 ...

row_max is already in log2(scaled) space (S * scale_log2), so
old_row_max - row_max_safe is the correct exponent for exp2.
The old code computed exp2(scale_log2 * (old_row_max - row_max_safe))
which is exp2(scale_log2^2 * (old_max_S - new_max_S)) — wrong.
