Configurable "Repeat for confirmation:" text
It would be nice to be able to set this prompt confirmation text.

This is also something I'd like, and I'd be willing to submit a PR for this if it can make things faster, but I wonder if it would have any chance to be merged when I see the amount of unanswered issues and PR's. If the repo owner passes by, do you think it would be worth it to work on a PR?
I can't comment on whether it will be merged in or not, but you are welcome to submit a PR.
