fix(clap): line wrap on strings that contain ascii control characters

[hargut]

counting ascii control sequences leads to unpredictable line breaks on colorized inputs (e.g. syntax highlighted strings)

#4360

Thanks! What is bothering me is that I can't find the origin of this code. textwraps code doesn't look like this. I rewrote some of the code but this doesn't look like something I wrote...

It looks like it originates from the textwrap crate. https://github.com/mgeisler/textwrap/blob/master/src/core.rs
At least parts of the comments are equal, and it seems that textwrap also added the skipping of ansi control characters at some point.

Eventually it was included due to an extension/fix?

The textwrap implementation is very different and hasn't changed since I copied other code over from it.
