Yes.

And that is more elegant. I had rejected using 'save-excursion'
because I thought point had to move in the case where the scrolling
had to happen. But in fact it is only the window that needs to move,
and the window position is _not_ preserved by 'save-excursion'.

Hmm. I guess I thought the window position _was_ preserved by
'save-excursion'. But the doc for 'save-excursion' does not say that.
