Hello,

I constructed a polyhedron with borders with the incremental builder (the
borders are simply defined as edges which does not have an opposite 
counterpart
in any other face constructed), and the polyhedron I get does not recognize
these edges as borders (size_of_border_edges() produces 0). If I subdivide 
this
polyhedron (say, using CC subdivision), the border edges are finally revealed.
Is this a bug, or did I forget to do something?

Amir.
