handle degenerate cubic loops
fuzzer generated a cubic with a very tiny loop at one end.
Breaking the cubic in two generated a piece so small it was
discarded, passing the original along.
Instead, use the loop detection as a hint that passing
the original may fail further along. Keep the big piece,
which is more linear than the original;
and change its end to match the original input if the
small piece isn't worth keeping.
