Earlier he said:

: (I can't just change them to buffer-substring-no-properties because I
: support xemacs, too.)

Except that 'buffer-substring-no-properties' is in xemacs21 !

If it's not in xemacs20 (I can't check for you) then define it in your
code:

(or (fboundp 'buffer-substring-no-properties)
    (defun buffer-substring-no-properties (beg end)
      "Return the text from BEG to END, without text properties, as a string."
      (let ((string (buffer-substring beg end)))
        (set-text-properties 0 (length string) nil string)
        string)))

By coincidence, I recall cutting this snippet out from an early version of
Per's custom.el.
