bug#7105: 23.2; walk-windows docstring "WINDOW"

[Kevin Ryde]

The docstring of walk-windows says,

    ALL-FRAMES nil or omitted means cycle through all windows on
     WINDOW's frame,
    ...
    Anything else means cycle through all windows on WINDOW's frame
     and no others.

but I couldn't tell what WINDOW is referring to there.

Is it too much cut and paste from `next-window'?  Does "WINDOW's frame"
in each of those places in fact means the selected frame, per the Emacs
22 docstring?
