Comment (by Sarat Chandra Addepalli <s.addepalli@…>):

 Hi. This seems to me to be more of a question on convention followed, than
 a bug. If a point set S has only two elements (p1 and p2, say) Should the
 Convex_hull(S) have two edges or one? One edge would mean that the
 Convex_hull is not a 'closed' polygon. Two edges, on the other hand, would
 mean that the perimeter calculation is correct.

 On a side note, I had to include the
 `#include<boost/geometry/geometries/point_xy.hpp>` line to avoid
 compilation errors in the attached file.
