 such cases, boundaries would not be written twice. Basically a boundary
 would be written out if the centroid of any of its two areas has a cat
 value which is in the list. I would like to see that option/functionality
 in `v.out.ascii` because most of the time the vector objects a user works
 with are points, lines, areas. Modules/libs then take care of appropriate
 handling of boundaries and centroids.

 I have modified r48886 to avoid segfaults and r48887 to open vectors with
 topology only when needed (partially restoring original behaviour to
 support fast export of massive point vectors).
