Colouring diff-part of an email

[Adam Sjøgren]

  Hi.

I am on a couple of mailing lists at work that receive an email per
commit in a source code repository.

Each email starts with some information about the commit - author, date,
revision, commit log message, and then the diff follows.

Has anyone written something that will colour an inline diff in an
email?

If I jump to the *Article* buffer and turn on diff-mode, the whole
buffer is coloured - which is a little much, headers become dull grey
etc.

I guess I just need some kind of washing, but I don't know quite where
to start, so I thought I'd ask if anyone already has solved the problem
:-)

I could change the email to be more MIMEish (inlining the diff-part),
but I think those of my colleagues who do not use Gnus would be annoyed
when their mail clients start to show the diff as an attachment.

  Best regards,

    Adam
