The doc (string and Elisp manual) does not say what args the functions
are expected to accept.  It says only that the hook "is called once in
each window that is about to be redisplayed".  Calling a funtion "in" a
window is not the same as passing the window to the function.  As it
stands now, the most usual reading of that "in" is that the function is
called with the window selected.  And if nothing is said about arguments
then a reasonable assumption is that no arguments are passed.

You are again reading a doc string in an old Emacs version.  the
current doc string does describe the argument with which the function
is called.
