Set sigint to true by default

[iONinja]

Hi there,

I was using this utility, and was caught by surprise by it's behavior in response to a ^C.

I feel that the default response should be what happens traditionally. It's great to have this option, but the default should be what most people probably expect.

Thanks!

No, I think it's fine like currently, Ctrl+C to escape input, Ctrl+D to escape process
