If your list is of triangles, three vertices with the same coordinate will give a degenerate triangle -- one that is guaranteed not to render. Similarly, use four of the same vertices for a quad, etc. It should be pretty easy to add support for zero-length vertex lists; I'll look into it for pyglet 1.2.
