Thanks, indeed. However, the problem is that it is missing the number
of nodes.

Another problem with v.info's output is also that it is hardly
parsable. A -g flag would be a very nice addition to v.info.

Just for the record, also the number of primitives would be usefull. I
know it's a summary of all the primitives present
(centroids+boundaries+lines+points), but it wouldn't do harm to mention
it too, and it could be usefull.
