Which makes the author of git-blame weep X-<.

The real issue is that embedding pathname in blob does _not_ help "git blame" but would actively hurt it. A file with the identical contents moved between the parent to child commit shares the same blob object and same object name in the real git. Jon's modified system that hashes pathname together with the contents would have them as two completely unrelated objects with different object names, which only means that even 100% similarity rename case becomes as expensive to find as renames of lower similarity, which needs to expand and look into blob contents.
