That worked, as you already know.

However, as the above code does not seem to run on slightly older Emacs
versions, I tried to convert it to:

--8<---------------cut here---------------start------------->8---
  (defadvice vc-diff (after leuven-vc-diff activate)
    "Push the auto-refine function after `vc-diff'."
    (my--diff-make-fine-diffs-if-necessary)))
--8<---------------cut here---------------end--------------->8---

... which does not work.

What am I missing?

Best regards,
  Seb
