Done: http://debbugs.gnu.org/cgi/bugreport.cgi?bug=7987

Doesn't seem as if there's that much interest in fixing this; or at
least, no one has replied....

Well, yes--I meant that if those refill problems in message-mode were
fixed, adding hooks would be an acceptable way of dealing with the
multiple-quoting highlighting. For the moment post-mode is solving this
problem more or less satisfactorily, but I might switch to mail-mode
(with hooks for the quoting) just to stay with something that's core
Emacs.

Thank you.
