Short description of error
EdgeSplit Modifier doesn't produce separate faces if Split Angle is set to 0 and the mesh (or part of) is a flat object.

For example: Create a grid object with subdivisions greater than 1 and add an EdgeSplit modifier with Split Angle set to 0. Splitting the mesh now to loose parts or working with a Smooth modifier shows that the modifier didn't produce the desired effect.edgesplit_broken.PNG

In fact, we need special handling for both limit cases (180° == no split by angle, and 0° == split on all edges).
