prompts captures Ctrl-W "cut word" shortcut as control character

[johnmaguire]

Describe the bug

When using the readline emacs Ctrl-W shortcut (available in bash and zsh), which is a shortcut for "cut word," removing the previous word from the prompt, the action works but leaves control codes in the input.

To Reproduce

Steps to reproduce the behavior:

1. node example.js
2. Ctrl+W, Ctrl+W, Ctrl+W, foo

{
  twitter: '@\x17\x17\x17foo',

Expected behavior

Ideally, cut word works and there are no control codes. Second best option is that Ctrl+W is ignored (#330 appears to do this.)

System

• OS: macOS
• Terminal: zsh
• Node version: v16.13.1

Additional context

These seem as though they should be supported by node readline: https://nodejs.org/api/readline.html#tty-keybindings
