--- Comment #4 from Roman Lebedev <lebedev...@gmail.com> ---
e465f9c3036b28bdbdbef03eee8fd022a3b6dcbf taught negator about the subj
transform,
since it does appear to be beneficial always.
The C0-(C1+X) case, however, is not generally beneficial,
so i simply moved it's specific fold earlier, so it fires again for C0=0.
