Diffing comments is surprisingly hard. In difftastic, I'm colouring the whole changed comment, but also underlining the changed words. This works OK, but punctuation is harder to read (see second image) and sometimes there's code in comments (see third image).

Git 2.17 has some really nice diff tweaks: colouring lines that have moved without modification, and even showing context by function rather than just N lines!
