Function quest::editor

pub fn editor(name: &str, message: &[u8]) -> Result<String>

Ask the user to enter some text through their editor.

We'll check the VISUAL environment variable, then EDITOR, and then finally default to vi. The message will be the initial contents of the file, and the result will be the final contents of the file, after the user has quit their editor.

On Windows, the editor defaults to notepad.
