Include comparison with git/contrib/diff-highlight

The comparison table in the README is great (I wish more projects did that!), but it looks like the diff-highlight script that is included in the git project is missing from it. It would be great if it were included as well.

Here are some screenshots that show some differences:

Thanks again. I wasn't aware of diff-highlight when I made that README content. Is it right to say that diff-so-fancy is built on top of diff-highlight?

I wasn't aware of that! It makes sense — those files are identical for the most part. I'd say diff-highlight should be mentioned in the title of diff-so-fancy column, just to help people who may not be aware of the close relationship between the two :)
