Bug: Color prompts break newline triggering

[Samuel Cordero Rodrigo]

Readline8.2-release installed from brew running on a 2017 Macbook Pro with Mac OS Mojave.

 When adding color escape sequences like \x1b[32m, readline seems to break first newline toggling for long lines (screenshot attached).

To reproduce just add a color prompt like prompt="\x1b[32mTEST\x1b[0m", call readline(prompt) and write a bunch of chars. An easy fix might be replacing strlen with an ad-hoc solution that doesn't count those chars.

Have a nice day!
