[GRASS-dev] Vect_get_area_boundaries() and negative ids

[Martin Landa]

Hi,

ids of area boundaries can be negative (N2->N1), I think that
Vect_get_area_boundaries() should return list of non-negative ids [1].

Vect_list_append(List, abs(line));

Similar for Vect_get_isle_boundaries() or am I wrong?
