I do not speak ruby (well I suspect I could read it if I wanted to but I didn't try) so this may or may not be something Johannes inherited from the original, but I think the code overcounts blobs and trees for a top-level tree that happens to have the same blob (or tree) twice. I am not sure if that is intended.

Overcounting would give closer estimate for how big a tar archive would be, or how big an populated working tree would be, so it could be considered a feature. It all depends on what this tools is useful for, I guess.
