ProcessBuilder Allow Use of raw_arg for Command on specific platforms

[jonatino]

Problem

rust-lang/rust#29494
rust-lang/rust#92939

Right now when using ProcessBuilder::exec_with_streaming, it uses the cmd.arg() method to build the Command which on Windows, does not allow us to pass in args that are in quotes (see the above issues for more information).

Steps

No response

Possible Solution(s)

It'd be nice if we could specify if an arg is "raw" or not, or have some other work around.

Notes

I'm using the cargo-quad-apk crate which uses cargo-util for executing a build command. The problem is, if your project has spaces in the name on windows, the Clink-args escape incorrectly and cause the tool to fail to resolve paths.

Thanks for the proposal. However, does switching to raw_arg really help? It seems not to me accoriding to this rust-lang/rust#30947, as it might be an issue of how rustc parses link-args. It would be good if you can try patching cargo-util and see if it works.

Also note that, as cargo-util is not an intentional artifact released by the Cargo team, there is no guarantee any API won't be removed in the future.
