A much bigger set of improvements to the git diff output is also easy to add: https://github.com/so-fancy/diff-so-fancy

This makes your git diff highlight the actual different characters between two lines, makes file names easy to see (and easy to copy, due to no a/ b/), makes renames and blank lines clear and readable.

It is so nice to get all this without a separate GUI diff visualiser when doing anything git-related from the command line.
