Would one of the expert debuggers please turn attention to this issue?
We need to figure out what is happening in this simple test case.

For some reason the command:

   (easy-menu-change '("file") "Print" pr-menu-spec "print-buffer")

has no effect just after step 5.
The command above is correct, but has no effect, that is, "Print" 
submenu is not created.

But if after step 5, you do:

    5.1 C-h v global-map RET    ;; create *Help* buffer in another window
    5.2 C-x o                                 ;; switch to *Help* buffer

Now, all works.
