This has been reported several times now.
It is related to changes Richard made to xdisp.c some time ago.
The change was intended to fix a problem with scrolling leaving a
partially visible line at the bottom (or top) of the window -- but the
change doesn't work correctly when that line is the last (first) line
of the buffer.
Is someone working on fixing this, or should I give it a try?
