Emacs configuration in .muttrc

[Gian Piero Ascenso]

Hi!

        I'm a new mutt 1.2.5i  user and I need some help
to configure Emacs as my editor. Actually it works fine,
but when I have just to write the Subject and nothing else
(as when subscribing to a mail-list) I hit ^X^S then ^X^C
to exit Emacs and the message is aborted. My current
.muttrc line for the editor has:

set editor="emacs -nw"

What'd I do?
