I vaguely remember that thread, but I couldn't find it on the web.  In
any case, I think it's not too complicated (everything worth doing in
Emacs requires a basic knowledge of Emacs Lisp):

(setq message-log-max t); Emacs Lisp!!!

(with-current-buffer (get-buffer "*Messages*")
  (setq buffer-file-name "~/.emacs_messages")
  (setq buffer-offer-save t)) ; just in case

(defun save-messages-buffer ()
  (with-current-buffer (get-buffer "*Messages*")
    (save-buffer 0))) ; or just (basic-save-buffer)

(add-hook 'pre-command-hook 'save-messages-buffer)
(add-hook 'post-command-hook 'save-messages-buffer)
