The --help text says this should only be passed when running tests; I don't see that reflected in the code. So which one is right and which one is wrong?

It is reflected in the code:

rust/src/bootstrap/src/core/config/flags.rs

Lines 462 to 469 in c0ddaef

pub fn rustc_args(&self) -> Vec<&str> {
match *self {
Subcommand::Test { ref rustc_args, .. } => {
rustc_args.iter().flat_map(|s| s.split_whitespace()).collect()
}
_ => vec![],
}
}

I will make the comment more clear.
