In /bin/mail, when composing a message, a double-interrupt should kill
the letter. (^C^C) The first interrupt is caught, but the second is not.
Pressing ^D -after- the second (or more) ^C will kill the letter.
mybox:~> mail fakeuser
Subject: test double-intr
This is a test.. ^C
(Interrupt -- one more to kill letter)
mybox:~> rpm -qf `which Mail`
