R0 or C0 would not happen in real life, so 0% is a moot issue.

However, wasn't that you who did follow that "certain numbers are special" logic in diffstat?

You advocated "diff --stat" should draw at least one +/- for a patch that adds/removes lines. And I (and others) agreed because zero is special in the context of that application.

I think reserving R100 to mean "identical byte sequences" has value, when people look at --name-status output, in the context of "similarity index".
