This misinterpretation could have been prevented by not giving Alt+O
any function, and by making it unbindable, just like Alt+[.

Luckily, by default Alt+O is bound to something that the user will
seldom or never use -- they either set morespace in their ./nanorc
or don't use it at all.  I can't see anyone toggling it now and then,
and if they do, they probably wait to see the result.  So the risk of
that keystroke ever being misinterpreted due to succeeding keystrokes
is virtually nil.  (Famous last words.)

(I now see that typing Alt+[ results in the message "Unbound key".
It should probably say "Unbindable key" or "Incomplete sequence"
instead.)
