Demonstrate that just like commit walks, object walks can have their
order reversed. Additionally, add verbose logging of objects encountered
in order to let contributors prove to themselves that the walk has
actually been reversed. With this commit, `git walken` becomes extremely
chatty - it's recommended to pipe the output through `head` or `tail` or
to redirect it into a file.
