reline handles ^C differently than readline

[hanazuki]

When user types ^C (ctrl-c) during Readline.readline, SIGINT is sent to the program, which in turn converted to an Interrupt exception. Reline.readline, however, returns a String with "\x03".

By bisecting I suppose this behaviour change was introduced in 8670d33 (#54)

Steps to reproduce:

1. Start bundle exec bin/example.
2. Type ^C.
3. Expect the program to halt.

Thank you for your reporting. I'm always troubled by the behavior but I forgot to fix it because I'm always troubled by other insanely many bugs. It's about time I'll fix it preferentially. Please wait a little longer.
