Bug?: Split

I was rebuilding parts that worked in V7 in V8. In the attachd I have a closed polysrf and a surface. If I split the polysrf with the surface, I get a bad surface.

The surface for splitting is bad. It is folded back on itself, and also has a kink. Move the 5 CPs at one end in the z-axis direction to see for yourself.

Then the bug is the sweep2 that created the surface. Let me dig that up.
