You might want to try diff-highlight from Git's contrib/ directory. It was the reason I added interactive.diffFilter in the first place. E.g.:

  cd contrib/diff-highlight
  make
  cp diff-highlight /to/your/$PATH
  git config --global interactive.diffFilter diff-highlight

It's not quite the same as a word-diff, because it doesn't find matches across word boundaries. So if you re-wrap a paragraph, for example, it won't be much help. But I do find it useful (and also as a general filter for log and diff output).

I think this thread can serve.
