No libsyntax folder for nightly toolchains

[gbip]

Hello,
It seems that the libsyntax folder is not downloaded on a nightly toolcahin.
Yet it is downloaded for the stable toolchain.
My guess is that rustup component add rust-src only add the component for the currently active toolchain.
In that case maybe you could make the readme more explicit about downloading rustc sources files for a nightly toolchain.
Thanks,

Thanks for the report @gbip.

This sounds like an upstream Rust issue. I have filed it there: rust-lang/rust#42667
