It is because of the recently added auto-window-vscroll feature (to scroll through tall images rather than jumping over them). To make reliable judgement about the display state, line-move must call sit-for which does redisplay. It would be useful to have a version of sit-for which did redisplay _internally_ to know what the window would look like if actually drawn, but without actually updating the display. I guess it would be possible to do this, but definitely not before the release. -- Kim F.
