Hi,
Somewhere between c477f20 and 88bc833 (10 commits), the cursor appears
to be displayed incorrectly when navigating to the last line of a
buffer. For instance,
1. emacs -nw -Q
2. ^P
3. ^N
Cursor is now shown at the last column of the frame. Insert `C-x 3`
between steps 1 and 2, and one should notice the cursor being displayed
in the wrong window.

Yes, this is fallout from the "Qnil is zero" change. The display
engine relied on the fact that a zero value in C was a Lisp integer,
but now it's a symbol, and all hell broke lose.
Fixed in commit daa18b5.
Thanks.
