Can we handle these errors differently? The command will fail if rustc isn't found or something, and the status will fail if rustc exits with an error. That said, they shouldn't really fail, so I think we can just panic here, maybe with an .expect.
Also, if we're calling rustfmt here, we can remove the rustfmt run in snapshots.rs.

I don't think a panic is appropriate, as this is just an extra convenience for the user and not a hard requirement of the transpilation process. The transpilation should still succeed if rustfmt is not installed or doesn't complete for whatever reason. Though unlikely, rustfmt may not be installed even if cargo and rustc are.

Could we make this optional (with a command line argument)?

Why would we not do it, though?

rustfmtwhen translating #742.Rather than running
cargo fmt, this runs therustfmtbinary directly so that it can be used on individual files, and also when there are no build files.
