I now tried to get that as well in Gnus emails. I often receive emails
with Diffs inside them, and they're correctly highlighted (thanks to
some Gnus black magic):

--8<---------------cut here---------------start------------->8---
    ;; regexp matching diff groups
    (setq mm-uu-diff-groups-regexp ".*")
--8<---------------cut here---------------end--------------->8---

Though, with your above suggestion, those mails aren't auto-refined...

I tried adding the following:

--8<---------------cut here---------------start------------->8---
    (add-hook 'gnus-article-mode-hook
--8<---------------cut here---------------end--------------->8---

but it doesn't help.

Any other excellent idea?
