There's no horizontal scroll.  What happens is that Emacs decides that
the mini-window's display will start at EOB.  I hope I've explained
why this happens in my previous message.

With a minibuffer-only frame, mini-window resizing works very
differently: it resizes the entire frame.

I'm sure we will welcome patches to make this happen in the other
cases.
