> I just found a difference in distances calculated with grass6 and grass7
for points to areas (see explanation in #2401). Needs checking.
G6 and G7 produced nearly identical results after the last change to
v.distance in trunk, but now (r61978) there is
Vect_line_geodesic_distance() available in trunk and v.distance makes use
of it (r61979). The results in latlong are now more similar to the results
in the original NC projection. In particular, the larger deviations
present in G6 have now disappeared in trunk.
