 This task is reverse of #9217.

 If model of a polygon specifies non-closed rings (first point is not
 repeated at last position), then this specification should be respected
 while consuming polygon encoded in OGC WKT format in which all rings are
 always closed.

 For example, the point number assertion below should hold:

 {{{
 using namespace boost::geometry;

 typedef model::point< double, 2, boost::geometry::cs::cartesian > Point;
 typedef model::polygon< Point, false, false > Polygon;

 Polygon p;
 read_wkt("POLYGON((1 1, 5 1, 5 5, 1 5, 1 1))", p);

 assert(p.outer().size() == 4);
 }}}
