That is not counting the 8000+ web pages containing Emacs-21.4...

This assumes that most version numbers in the text can stay ("will be
available with version xxx" is a good candidate).  That will still
need to cater for "the current version is xxx", but maybe _those_ can
partly be autogenerated with CVS keywords, depending on the kind of
text?  In AUCTeX, we have something like

(eval-and-compile
  (defconst AUCTeX-version
    (eval-when-compile
      (let ((name "$Name:  $")
            (rev "$Revision: 5.482 $"))
        (or (when (string-match "\\`[$]Name: *\\(release_\\)?\\([^ ]+\\) 
*[$]\\'"
                                name)
              (setq name (match-string 2 name))
              (while (string-match "_" name)
                (setq name (replace-match "." t t name)))
              name)
            (if (string-match "\\`[$]Revision: *\\([^ ]+\\) *[$]\\'" rev)
                (format "CVS-%s" (match-string 1 rev)))
            "unknown")))
    "AUCTeX version.
If not a regular release, CVS revision of `tex.el'."))

It's less than perfect, but at least it is something one can't
forget.  It also means that you need to export using the version tag
when doing a release.
