I haven't looked closely at the vi code, but would be easier/simplier
or just plain more-hacky to just not try to put the cursor in the last
column of the last row?  Already it deals with status messages longer
than (window-width) chars by doing a multiline status message, so maybe
just tweak that logic to kick in for (window-width - 1)?

Or Brett can fix a complicated scenario :).

Simon.
