I just put
(global-set-key [?\C-q] "\C-x\C-s\C-x\C-c")
into my ~/.emacs file and it works just as one would expect, both when
emacs is running in a separate window (which disappears) or when emacs
is running with -nw in an xterm (the xterm is unaffected).

I will finish composing this email (in emacs -nw) by typing ^q and
expect to be left in mutt, whereupon I shall press y to send it.
Is that what you wnat?
