arphaman added a comment.

I think I'd rather move `clang-rename` first.

       FindingAction.getUSRList();
   const std::vector<std::string> &PrevNames = FindingAction.getUSRSpellings();

So while it's correct this copy seems to be unnecessary (pls, correct me if i am missing smth) and the fix is easy. If you want i can send a separate diff or i don't mind smb else fixing it.

Thanks for the feedback! I agree with your comments, but would prefer to leave them for a separate patch. I have some similar fixes for some of this code as well.
