When I use emacs -Q, it reads correctly in the *Help* buffer (calling 
describe-variable)

--8<---------------cut here---------------start------------->8---
    use the quoted symbol instead: 'font-lock-warning-face
--8<---------------cut here---------------end--------------->8---

But then, I see in the *Help* buffer

--8<---------------cut here---------------start------------->8---
    use the quoted symbol instead: \='font-lock-warning-face
--8<---------------cut here---------------end--------------->8---

So we must modify help-fns--var-obsolete to use
substitute-command-keys. I've changed it, and I've reverted my
patch. That should be OK then.

Best regards, Michael.
