Now that looks useful, except for one thing.  In 20.7, if I have
several windows displaying the same buffer, and type C-x < in one
of them, the window-scroll-functions get called for each of those
windows in top-to-bottom order.  My code then doesn't know which
window's hscroll value it should copy to the others.

If I scroll a window vertically, only that window is reported to
the window-scroll-functions.  Is the behavior with hscroll a bug?

I guess I could work around it by storing the previous hscroll
position in a buffer-local variable... but I'd rather not.
