--help message displays poorly in 80-column terminals

The help message displays very poorly in 80-column terminals. If possible, the message printing should be terminal-size aware.

I believe clap 3 has this functionality, but bindgen is using clap 2 at the moment

There doesn't seem to be any clap 3 in the registry?

(But anyhow patches more than welcome :))

Given that clap 4 is releasing soon-ish (https://epage.github.io/blog/2022/09/clap4/). Migrating from clap 2 would be a good move because it is entering maintenance mode.

We're using clap 4 so this shouldn't be an issue anymore.
