When the highest used article number of an empty newsgroup is n, INN currently reports low=n+1, high=n.
We should instead report low=n, high=n-1 in accordance with RFC 3977 which recommends that the high water mark is one less than the low water mark.
Besides, the reported low water mark currently exceeds 2^31-1 with that rule:
GROUP trigofacile.test.maxartnum
211 0 2147483648 2147483647 trigofacile.test.maxartnum
This should be fixed, and make sure that the reported high water mark cannot be negative.
