[Feature Request] Option to escape special characters or quote strings containing special characters

[brianstrauch]

Feature Request

A common use of go-prompt is adding autocompletion to CLIs. Occasionally, a CLI will want to autocomplete an argument or flag value with special characters. Right now, rendering these values to the terminal causes syntax errors.

A new option should be created, such that when added to a prompt:

• Characters such as $ are escaped before rendering.
• Strings containing spaces are surrounded with quotes.
