I like the count->sstables rename and incorporated that, as well as changing the order.  I considered preserving it since that wouldn't be a huge deal, but since this is trunk I think a major upgrade is a fine time to change it.  I also update the doc, but left the array allocation Aleksei commented on since I think that reads cleaner and performance isn't a huge concern in nodetool, and even so this would be very minor.

> It would be helpful to know at a glance how many sstables are involved in any running compactions. While this information can certainly be collected now, a user has to grab it from the debug logs. I think it would be helpful for some use cases to have this information straight from {{nodetool compactionstats}} and then if the actual sstables involved in the compactions are desired, dive into the debug.log for that. I think it would also be good to have this information in the output of {{nodetool compactionhistory}}.
