Thanks for the answers. So it seems it's not a bug, but may lead to new merge options. I worked around it anyway, so it was not a real problem.

Adding such an option, similar in nature to the flags for turning off renaming detection entirely (merge.renames, diff.renames, -Xno-renames) would probably make sense (I don't see an analogy to -Xrename-threshold=, though). It might make sense as just an alternate setting of merge.renames or diff.renames, though it's possible that could get confusing with "copy" being an option. #leftoverbits for someone that wants to figure out what the option names and values should be?
