bugfix for T49593: _gen_meshface removes points from a 3DFACE or SOLID if the they share the same location. This was a good a idea but it was not implemented completely. Now it is: faces with overlapping verts get imported as edges if the remaining geometry has only 2 verts. This allows the user to easily select all edges if extraction is needed to make it visible in a rendering. (e.g. select one edge and then choose Select > Select Similar > Amount of connecting edges).
