Fix ++mull:ut's handling of $tune.
arvo's sys/hoon.hoon defines the $tune case as:
{$tune *}
[(face p.gen sut) (face p.gen dox)]
Fix the C jet so that it doesn't use sut on both spans.
case c3__tune: p_gen = u3t(gen);
_mull_used();
{
- return u3nc(u3qf_face(p_gen, sut), u3qf_face(p_gen, sut));
+ return u3nc(u3qf_face(p_gen, sut), u3qf_face(p_gen, dox));
}
case c3__burn: p_gen = u3t(gen);
