We don't turn on copy-detection in "git status" by default (only rename detection), and I think you are right that there is currently no way to turn it on manually. However, it would probably be sensible to handle "C" diffs in your parser, if only to future-proof against a day when that changes (and because it should fairly trivial once you build "R" support).

I don't know if anybody is actively working on such a change, but somebody expressed interest recently-ish:
