[[!tag obnam-wishlist]]
It would be nice for Obnam to have a tool to answer the question
"how much space will be freed if I remove these generations?"
- need to find list of chunks that are used only by the specified gens
- perhaps also count B-tree reduction? cound nodes that are unshared by
the relevant trees, or only shared by the trees to be deleted
- however, the B-trees are going to be a fraction (a few percent) of
the size of the chunk data, so they're not really worth it
