rain deploy: Hitting enter on Do you wish to continue, assumes Y #727
Description
Due to having a fair few parameters it can be habitual to hit enter a few times.
One too many and you accept the change set - even if it hasn't calculated it yet - as it will remember you hit enter and as soon as it hits the Do you wish to continue it eats that last superfluous enter, assumes Y, and continues.
Ideally all input would be eaten before asking a question. And Y would not be assumed for a Do you wish to continue. It should repeat the question until either Y or N is entered.
Being able to --use-previous-parameters would help too. Using -y accepts existing parameters but also accepts the changeset without asking.
