Fair enough. Here are some patches (to go on top of jk/rev-list-disk-usage,
though obviously the first one could be applied independently).

It's already big and scary enough that I prefer starting an EXAMPLES
section. :)

By the way, there's one other finishing touch we might consider:
enabling --use-bitmap-index automatically when bitmaps are present, for
requests that produce the identical answer (so _not_ a regular
traversal, because the output order and presence of pathnames are
different there). I'd prefer to do that as a separate series, though,
since there are multiple arguments that might benefit (like --count).

  [2/2]: docs/rev-list: add some examples of --disk-usage
