Log message:
        (Selecting Windows): Clarify descriptions of
        with-selected-window and get-lru-window.
        (Cyclic Window Ordering): Refer to particular frame when talking
        about how splitting affects the ordering.
        (Displaying Buffers): Fix descriptions of switch-to-buffer and
        switch-to-buffer-other-window.  Explain how setting of
        display-buffer-reuse-frames affects pop-to-buffer.
        (Choosing Window): Clarify some details in descriptions of
        display-buffer-reuse-frames, pop-up-frames, and
        pop-up-frame-function.
        (Dedicated Windows): Clarify some details.
        (Textual Scrolling): Replace term vscroll by term vertical
        scroll position.
        (Vertical Scrolling): Fix typo.
        (Window Hooks): Relate text on jit-lock-register to window
        scrolling and size changes.
