bug#10354: 24.0.92; `window-min-height' is no longer DEFVAR_INT

[martin rudalics]

Section 11.14 Variables with Restricted Values of the Elisp manual
contains the following text:


   Variables of type `DEFVAR_INT' can only take on integer values.
Attempting to assign them any other value will result in an error:

     (setq window-min-height 5.0)
     error--> Wrong type argument: integerp, 5.0


This text is no longer valid since `window-min-height' is now defined in
window.el.
