Both are correct, but the output phase happens after diffcore_std() cleans
up the unused and unchanged filepairs thrown into the queue for the
purpose of find-copies-harder, so you shouldn't have to worry about them.
When you rename a file without changing its contents, what do you want to
see in --dirstat-by-file output? I assume that you do not want to show
anything, so it would be sufficient to compare the two object names.
