At first sight, having the subject starting with numbers seemed quite
disturbing to me.  But you're right, the lesser the better.

So we're going for something like

  (string-match "^\\(\\([.0-9]+\\)*\\)\\.[0-9]+$" emacs-version)
  (setq topic (concat (match-string 1 emacs-version) "; " topic))

Question: do I have to make a special case for MS-DOS?  This would be
because loadup.el does not seem to compute the same emacs-version for
MS-DOS:

;; Determine which last version number to use
;; based on the executables that now exist.
(if (and (or (equal (nth 3 command-line-args) "dump")
             (equal (nth 4 command-line-args) "dump"))
         (not (eq system-type 'ms-dos)))
      [...]
      (defconst emacs-version
        (format "%s.%d"
                emacs-version (if versions (1+ (apply 'max versions)) 1)))))
