Is the above supposed to be part of a doc-string?
A complete example is always helpful:

(defvar my-var nil
 "Blah.
Do stuff:
  (defvar bar 1)
  (foo \\='bar)
  (foo 'bar)
")
C-h v my-var

So I guess all existing lisp doc-strings everywhere are supposed to be
audited for use of ' and \= escapes added where needed.
(I believe it has been done for code in Emacs.)
This has been discussed several times over on this and other Emacs lists,
so there probably isn't anything new left to say.
