I don't understand this suggestion; doesn't it only catch duplicates where both instances were introduced in the same 100-commit range?

That has often or typically not been the case, in my experience. Often one version of the file or folder will have existed for some time (days, months, years), and then a "duplicate" will be introduced.

As far as I can tell this "diff large range" approach is quite expensive (37 seconds in a trivial test on this repo), and non-comprehensive.
