Missing Command::get_{args,envs}

[alecmocatta]

Tokio's std::process::Command wrapper, tokio::process::Command, is missing Command::get_args and Command::get_envs.

Can be worked around in my case, but would be great to have parity here. Bumped into this porting some code to tokio.

Thanks for the report! I'll try to take a look at this when I'm back from vacation next week.

If anyone wants take a shot at implementing it, feel free to ping me on the PR!

It looks like it's unstable yet.

Good point, though it's scheduled for stabilisation in a couple days' time: https://github.com/rust-lang/rust/blob/master/RELEASES.md#version-1570-2021-12-02

Unfortunately, our MSRV policy requires that we support compilers from at least 6 months back, meaning we won't be able to rely on these methods from the stdlib for 6 months... :(

I've opened #4295 to add a cmd.as_std() method which will allow the caller to access the underlying std::process::Command, and therefore the new methods (if their stdlib version is new enough)

@alecmocatta #4295 has landed in 1.15.0 so I'm going to resolve this for now. Feel free to reopen if you have other issues or questions!
