Oops, right.

Should v.info calculate bounding box and number of features for level 1? 
This can take some time because the whole coor file must be read, but I 
would find it useful to know the extends and number of points (, lines, 
boundaries, centroids) even for level 1. That helps setting the right 
region for the v.surf.* modules.
