Hot take: If we added a "--install" option to #curl, we could optimize many a "| sh -" pipeline away.

Finally a truly universal installer.

@larsmb 🤣 I was shortly thinking that that is a chicken/egg situation if you want to install cURL via the `--install` option... 🙈
@larsmb @heiglandreas Let's just do a Microsoft, and ship every OS with something that isn't curl aliased as curl.
@larsmb @heiglandreas @pianosaurus so if their curl also implement --install, one can indeed install curl via "curl".
