add_num_rangeand slightly less in
add_*works now. If e.g. you had a /24 and an adjacent /25 net with the same value before, adding a new /25 would have merged the new block with the existing /25, resulting in two adjacent /24s with the same value because only single-level merging was possible. Now the two will be merged to a single /23.
