ido-mode: Defining M-O breaks cursor key mapping

[Jorgen Schaefer]

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

When using emacs -nw and ido-mode, the cursor keys UP and DOWN
don't work as expected in the ido minibuffer. They seem to be
interpreted as sending M-O A and M-O B (in the shell, they send
^[[A and ^[[B).

ido-mode defines [(meta ?O)] to be 'ido-next-work-file for the
ido-mode-map. Removing that definition fixes the problem. It seems
this interferes with the key substitution process.

In GNU Emacs 22.0.50.1 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars)

configured using `configure '--prefix=/mnt/datengrab/software/emacs/2005-05-28'
