Symbol value of `font-lock-reference-face is void about ess HOT 6 CLOSED

font-lock-reference-face has been removed in Emacs 29 (it was previously obsolete). ess should use font-lock-constant-face instead.

Adding the following lines to my .emacs seems to fix the problem.

(defvar font-lock-reference-face 'font-lock-reference-face
  "Face for references in an Rd file.")
(defface font-lock-reference-face
  '((default :inherit font-lock-keyword-face)
    (((class color) (background dark))
     (:foreground "lime green"))
    (((class color)) (background light) (:foreground "dark green")))
  "Face for references in an Rd file."
  :version "0.0")

Thank you, @yantar92 ! -- indeed that's much a smaller change -- as @ralmond mentions (above), it appears only once, so I've committed and pushed the obvious fix.

@mmaechler I generally recommend going through the byte-compilation warnings thrown by just released Emacs 29. It will help avoiding such problems in future.

Just got this issue - fedora 39 ships emacs 29, and I have left over of older emacs ess . Btw, when is a release due?

It has been 18.10.3snapshot for a few years now.
