/bind bug

I think i found a bug, but i am not one hundred percent sure i'm not
doing something retarded so i wanted to email this list first, if it
is indeed a bug i'll switch to the -dev list (or not depending on
where this stuff normally goes =) )

basically i am wondering why the following doesn't work
/bind ^M previous_window
/save
/reload

the funny part about the above is that ^M is written to my config and
survives the /save and /reload so it is still shown if i do /bind ^M

and why after this ^P still works.
/bind -delete ^P
/save
/reload
this dosn't surprise me much as maybe unless ^P is bound to something
it is rebound automatically on a /reload so i am not sure if thats the
case or not but the above with ^M is what really makes me think there
is a bug somewhere.  i am running the latest irssi.

i am also on the list so no CC is needed.  Thanks!
