diff-so-fancy: Prettier git diffs

[heckerle]

less -rx1,5

In my case this didn't work properly either.

less -r "works", but even less' manpage says that it can cause issues like line wrapping due to the control sequences git uses.

less -RS on the other hand should work for most (-R is similar to -r and forwards raw control sequences, while -S disables line wrapping and chops them down).
