Your patch basically replaces some of the calls to scroll-{up,down} with
scroll-{up/down}-command, which I think makes sense, since this is
supposed to emulate the normal scroll up/down commands, as far as I can
tell.

But the patch no longer applies, and I don't use follow mode.  Could a
follow mode user say whether this is what they'd expect, and if so, spin
a new patch?
