Prompts do not handle long input strings correctly

[joshmarsh]

When the user responds to a prompt for user input, the prompter will repeatedly echo the string if it is very long. For example, responding to the dce auth prompt should look like this:

This may be an issue with github.com/manifoldco/promptui.

If this is really a bug in promptui, I'd recommend we scrap it.

I'd actually like to lean away from dependencies like this, where its trivial enough to implement ourselves.
