bug#6425: 23.2; Scrolling in a split window

[Konrad Podczeck]

Split a window vertically into two sub-windows, say A and B. Make A the
active subwindow. Now, without making B active, go with the mouse to the
scroll-bar of B and drag it. Then scrolling in both sub-windows
happens. 

This was not so with Emacs 22.
