Reverse order of -Zinput-stats and -Zmeta-stats output.
Currently they have the largest items at the end. I believe the rationale is that it saves you scrolling up through terminal output because the important stuff is at the bottom. But it's also surprising and a bit confusing, and I think the obvious order (big things at the top) is better.
