This bug report is unclear, and I can not reproduce any bug with
visual-line-mode under emacs -nw. Please provide a *precise* recipe for
seeing this bug, starting with `emacs -Q -nw'.

I think I have got the idea. It is because visual-line-mode maps "M-["
to previous-logical-line as in simple.el
=========
(defvar visual-line-mode-map
(let ((map (make-sparse-keymap)))
(define-key map [remap kill-line] 'kill-visual-line)
(define-key map [remap move-beginning-of-line] 'beginning-of-visual-line)
(define-key map [remap move-end-of-line] 'end-of-visual-line)
(define-key map "\M-[" 'previous-logical-line)
(define-key map "\M-]" 'next-logical-line)
map))
===========
But in terminal (-nw), arrow keys are actually "M-[ A" "M-[ B" "M-[ C"
"M-[ D". Hence letters "A" "B" "C" "D" will be inserted to the buffer.
To prove my idea, I tried:
(define-key visual-line-mode-map "\M-[" nil)
(define-key visual-line-mode-map "\M-]" nil)
and the issue is solved.
Cheers,
poppyer

That looks like a problem indeed. This said, since Emacs-23 uses
input-decode-map rather than function-key-map to decode M-[ A into an
arrow key, it should take precedence to the binding in
visual-line-mode-map. Can you check input-decode-map and
function-key-map to make sure that the mapping from escape sequence to
arrow key events is at the right place (i.e. not in function-key-map)?
Also, the terminals to which I have access use difference sequences than
the ones you show (which do ring a bell, tho). Could you give us some
details about the terminal you're using and its configuration?

Yes, they are in input-decode-map and not in function-key-map

I am using iTerm.app (http://iterm.sourceforge.net/) under MAC

Even xterm uses ESC [ for the function keys.

I believe you, I just don't know when: mine uses ESC O A, ESC O D, ...

That's why I wrote "function keys".

Ah, I see. Yes, as written, I agree with the fact that M-[ should be
avoided since it's used as escape sequence.

Under terminal (emacs -nw), the visual-line-mode maps the arrow key wrongly.
<up> -> A M-[
<down> -> B M-]
<left> -> D
<right> -> C
and it also maps the mouse-key of xterm-mouse-mode wrongly.
turn the visual-line-mode off will back everything to normal.
