Do emacs-snapshot -Q -nw with the attached file "nuk" in an xterm with
TERM=xterm: emacs does not place the cursor on the leftmost position in
empty lines but one charakter to the right.  If I then type a charakter
it displays at the leftmost position and the cursor does not move to the
right.  If I type a second character, this character displays at the
second column and the cursor moves to the right.  If I save the file and
use another tool to view it everything looks alright.
This only happens in terminal frames (tested on xterm and rxvt-unicode),
not in graphical X frames.
This bug has been introduced after emacs-snapshot 2010-10-30 and is
present in emacs-snapshot 2010-11-16.
See the attached screenshots which show the red cursor on the leftmost
position with emacs-snapshot 2010-30 and on the second column with
emacs-snapshot 2010-11-16.  This is on a rxtv-unicode terminal in a
screen (1) session.  The screenshots emacs-snapshot-one.png,
emacs-snapshot-two.png and emacs-snapshot-three.png show the cursor on
the second column, then with the first charakter of this very paragraph
typed ("S" leftmost, cursor on second column) and then with the second
charakter of this very paragraph typed.  These three screenshots are 
with emacs -Q -nw in an xterm.

It would be nice if the cursor would be on the leftmost position in
empty lines.

Thanks for your attention,
Gregor
