This revision now requires changes to proceed.


  Oops, the default value (5 vs 100) wasn't my point. I doubt if taking the first n
  candidates would be a good "heuristic."
  
  If I understand correctly, it may miss the copy information only if the file is
  out of the n-candidates list. I think it would be hard for users to understand
  why the copy wasn't detected. That's my concern.
  
  (marked as "request changes" to flag discussion is ongoing. no new version is requested.)
