`rustdoc 1.51.0-nightly` does not work

[kloenk]

When running make O=build rustdoc, rustdoc fails with the error error: too many file operands.

As far as I can see it, this is, as rustdoc does not support the @file cmd argument. I also found no documentation of this feature for rustdoc, which let's me wonder how it ever worked. Should we create an issue at the rust repo, asking for support for that flag?

This was implemented in rust-lang/rust#82261 will be included in rustc 1.52.0.

Ok. will leave this open, until rust 1.52.0 is merged in nixpkgs. installing newer rustdoc would be not that easy for me.

There is now an open pr onto staging for rustc 1.52.0.
