The following patch should fix it.  Unless somebody encounters an
error with it, could someone please check it in?

Regarding the implementation: I could write a compatibility function
for `window-body-height' in order to make calculation of the correct
position for moving point work in Emacs 21 as well.  But as there
haven't been any problems with this version of Emacs when putting
point into the scroll margin, it is probably not worth it.
