[AUCTeX-devel] Problem?

[David Kastrup]

I see

    @defopt font-latex-fontify-script
    If non-nil, fontify subscript and superscript strings.

    Note that this feature is not available on XEmacs, for which it is
    disabled per default.  In GNU Emacs raising and lowering is not enabled
    for versions 21.3 and before due to it working not properly.
    @end defopt

in auctex.texi, but font-latex.el contains

(defcustom font-latex-fontify-script (not (featurep 'xemacs))
  "If non-nil, fontify subscript and superscript strings.
This feature does not work in XEmacs."
  :type 'boolean
  :group 'font-latex)

So just _how_ is this disabled per default on Emacs 21.3 and before?
