No.  There are lots of variations on that theme.  For example, in
xemacs-packages/python-modes/pydoc.el, function pydoc-menu-enter, we see:

    (cond
     ;; GNU Emacs 19 or above
     ((and (not (string-match "XEmacs" emacs-version))
           ;; Version 19 and above
           (string-lessp "19" emacs-version))
     ...

which doesn't invoke match-string at all.  And then there is
xemacs-packages/gnus/lisp/nntp.el, which defines the variable
nntp-async-needs-kluge thusly:

  (string-match "^GNU Emacs 20\\.3\\." (emacs-version))

We should audit all of those string-match calls.  Some of them look wrong.
I see quite a few that just check the version number, with no
differentiation between Emacs and XEmacs.  There are quite a few looking for
"Lucid" only, and a number looking for "beta"!

Jerry, you're looking at this the wrong way.  Why should you care if

Good point.  If I build it, maybe they'll come. :-)  Well, like I said, I'm
not going to work on any of this stuff in earnest for a few months yet.
Still, I should  put what  little I do have out in public.
