Those changes

2002-02-13  Richard M. Stallman  <address@hidden>

        * bindings.el (mode-line-minor-mode-keymap): Definition moved up.
        Initialization moved up too.
        (mode-line-modes): Use :propertize.
        (mode-line-mode-menu-keymap): Var deleted.
        (mode-line-copied-mode-name): Var deleted.
        (mode-line-mode-name): Function deleted.
        (mode-line-mode-menu): Each item now shows its mode line lighter.
        (minor-mode-alist): Don't call propertize here.

mean that previously (at 21.1 and 21.1.90)

  (setq mode-name (propertize "my-mode" 'display '(height (+ 5))))

would work, while it does not now.
