When I added the `Task` stuff it wasn't with the idea that we'd use it for *all* subprocess invocations. I think in some cases we really just do want a `Command` instance without the extra wrappering. Add an implementation (there are many of variants of this out there in lots of Rust codebases) This makes sense to use instead of `Task` where we're using `.quiet()` so that we don't print the description, and especially where we don't expect the task to fail usually, so it's OK if the error message is odd.

I see you are using Command::new and not CommandRunExt above. I am not sure I follow how this gets wired. I imagine that now everytime someone uses Command::new it will use this instead, but have no idea how that is happening.

mmm I guess it's using trait and then the impl that wires this.

Right, the trait adds a new method.
