Typing Control-U in sphinx-quickstart clears the line

[asmeurer]

To reproduce, start sphinx-quickstart test, start typing something for the first answer, and press Control-U. The entire question line is cleared, rather than just what was typed.

Environment info

• OS: Mac
• Python version: 3.5
• Sphinx version: 1.7.4

This might be come from the fix for #3364. We have to use input() to protect prompt.

Maybe you just needed to wrap your ANSI escapes with \[ and \].

[tk0miya]

What did you mean? Wrapping all escape sequences with \[ and \]?
I'm not good at console manipulation. Please let me know your idea.

Thanks,

Actually it needs to be \1 and \2. Like \1ESCAPECODE\2. Those are \[ and \] in bash but not in Python. Those tell readline that the ANSI codes are zero-width (invisible). It's hard to find good docs on this, but it's mentioned at https://tiswww.case.edu/php/chet/readline/readline.html

Fixed by #5059.
Thank you for reporting.
