This is however a bit of a tricky crate. Since this crate is injected into processes, I think it might actually best if this doesn't rely on uucore. In this case I think we should just check what error messages GNU gives and just use eprintln! and std::process::exit to match that.

@sylvestre do you agree?

Edit: Actually, I think we should probably only print a warning if we fail to parse the value.

Great! Just one small question

Great! Let's also remove the uucore dependency in src/uu/stdbuf/src/libstdbuf/Cargo.toml!

Great! Thanks!
