I still see the problem with the current branch head. Here are my settings:

(font-lock-add-keywords
 'emacs-lisp-mode
 `((,"\\\\\\\\|"
    (0 font-lock-keyword-face t)
    (0
     (prog1
         (compose-region
          (match-beginning 0)
          (match-end 0)
          ,"∨")
       nil)))))

Also, while the mode line became normal height, the echo area became x7
height instead. The buffer menu is fine.
