walk-window-tree does not return a result.

[Vladimir Nikishkin]

Dear Emacs Developers,

I have recently found out that `walk-window-tree' always returns nil.

Is this intentional? It would make sense, at least to me, to return
the "tree of fun return values". That would requires essentially, adding
a few calls to cons.

Does this make sense? I haven't created an issue, because I thought
that it might be intentional.

The nice thing about lexical binding is that you can have your cake
and eat it too... without spoiling other people's cakes :)

  (let ((wlist '()))
    (walk-window-tree (lambda (w) (setq wlist (cons w wlist))))
    (reverse wlist))
