These are the reasons why some of the stats stuff is different now:

- in general, updating the precise stats in borg is quite a pain. it's 
everywhere in the code and often it is in the way of easy changes / 
improvements of the code.

- at some places, borg had lists or hashes containing (chunk id, chunk 
size, chunk csize) information. i had to drop the "csize" (compressed 
size of a chunk) because it also was in the way - e.g. of easy, 
repo-wide recompression without having to update the csize information 
at all the places where it was stored.

- borg was often giving somehow unrelated infos. e.g. if you created an 
archive, it also gave you global repo-wide stats and not just the stats 
of the archive you just created. if that can be done quick, it's nice, 
but if it is slow (e.g. if it is a big repo, with lots of archives), it 
can be an unnecessary pain.

Likely that was also dropped due to the csize removal.
