 m Emacs RET

Observe this line near the middle of the window:

  For information on extending Emacs, see Emacs Lisp(elisp).

Use "M-x customize-variable" to customize the variable
Info-hide-node-references to a nil value.  Then return to the *info*
buffer.

Expected result: the above line shows the full reference, as in

  For information on extending Emacs, see *note Emacs Lisp: (elisp)Top.

Actual result: the display does not change, until you leave this node
and return to it, or manually invoke revert-buffer.

This is confusing.  The option should take effect immediately after it
is customized.

Bonus points for making its effect immediate when the variable's value
is changed through "M-x set-variable RET".
