Yes, that's exactly what I mean and want! Perfect, and very clever! That indeed moves point to the division between old and new text! Ah, but there's a missing feature... I'd like it to also work as I described when I use scrolling with a prefix argument. That is, it should move point to the division between old and new text even then. So M-5 C-v would move point to 5 lines from the end of the buffer. scroll-margin might interfere, but I still would want point to be at the division between old and new text.
