OK, I'll do this at the beginning of next wekk.

Just one question: Where should the lisp defvar go?  I didn't
find any suitable .el file in lisp/ at first glance.

Yes, will do.  I looked at the code, and I'm a bit confused
where to call such a  message-hook actually.
At first glance, I'd say in message3 in xdisp.c, but there is also message2
and the various no_log and dolog variants.

Also, should I define message-hook also in Lisp, and if yes, where?
