I agree with you on that.  Then again i've never run out of
memory with rsync.

Please no!  The -vvvvvvvvvvv is bad enough, don't turn stats
into the same abominat^Wawkwardness.

I have mentioned before that i would like to see selectable
logging.  Stats would fit into such a framework.  At the moment
we have three statistical summaries.  It should be possible
to select them individually.
