Hi Goffredo,
Why not show just the summary section by default and have a flag (-v)
for the details section?

"Type" for the first column is probably enough.
Why is the third column called Chunk-size? If my understanding is
correct, it's just a break down of Disk_allocated from the summary
section. If so, why not call it Disk_allocated to avoid confusion?
Also, why do you use dashes instead of underbars for table headers?
Thanks,
Ilya
