strange key handling on a terminal

[Dan Nicolaescu]

I am using xterm-215 that emits escape sequences for some key
combinations that did not emit any special sequence.

For example C-. emits "\e[27;5;46~"

Now if I do:

emacs -q -nw 
M-: (define-key function-key-map "\e[27;5;46~" [(control ?\.)]) RET
M-x global-set-key RET C-. RET indent-region RET

Then if I try pressing C-. I get the error: "C-. is undefined". This
happens when using emacs from CVS updated a few minutes ago.

The same thing works fine when using emacs-21.4

Does anyone know what is wrong? 

Thanks
