Escape sequence for deprecation notifier

[justindemars]

When I used to work at Google (techstop), we had an escape sequence built into deprecation notifier that techs could type in to kill the countdown. How can we configure this in our environment?

We removed that feature internally before we got around to releasing DN as open source. The sequence got shared and it lost its usefulness. It wouldn't be terribly difficult to re-add if there were interest in that, though we're pretty busy so I'm not sure when we'll get around to it. Happy to review PRs though.
