Unexpected behaviour when wrapping ANSI escape codes

[taylorconor]

Hello!

I understand that ANSI wrapping support was added in #140. However adding ANSI codes to the example string from the README produces unexpected line wrapping:

fn main() {
    let text = "\u{001b}[31mtextwrap\u{001b}[0m: an efficient and powerful library for wrapping text.";
    println!("{}", textwrap::fill(text, 28));
}

produces:

textwrap: an
efficient and powerful
library for wrapping text.

expected:

textwrap: an efficient
and powerful library for
wrapping text.

Hi Conor, nice to see you here :)

That looks weird indeed... I'll have to investigate a bit.

This is fixed in the newly released version 0.13.1.
