*  Fixes Segmentation Violation when exporting areas.

*  Fixes interior boundary winding (shapefiles have exteriors clockwise,
   interiors counterclockwise) for areas with holes.  AFAIK,
   Vect_get_area_points and Vect_get_isle_points always return clockwise
   polygons. So isle point orders are reversed. Isles will come up
   twice, once as interior and once as exterior. (If my understanding of
   these API's is incorrect, someone please let me know.)

*  Only labelled areas are exported unless the -A flag is given.  This
   makes possible the differentiation between area holes and area
   islands.  With the -A flag, all areas are exported.
