Vscrolling is not a user-controlled feature as such, and the current
description in NEWS is about Lisp functions behaving differently, but
with a user visible effect to fix short-comings of previous releases.

Also, I do not envision that a user would want to disable
auto-window-vscroll (so it is not a defcustom).

So I suggest to keep the above entry as is.

I have added the following description to the user visible changes:

** Moving or scrolling through images (and other lines) taller that
the window now works sensible, by automatically adjusting the window's
vscroll property.

IMO, the new functionality is "obvious", so I don't think it is
necessary to mention this in the Emacs Manual - and I don't know
what to write or where...
