I had to change this line in my local copy

to

  local args = { 'blame', '--contents', '-', '--incremental', '-C', '-C', '-C' }

I think It would have been nice if we could add settings to git blame command, to optionally add -C on blame. More info on -C with git blame: https://youtu.be/aolI_Rz0ZqY?si=0UGEs5VI6GGijyl1&t=713
