Macro documentation links to an empty page

The `macros` link [from the API docs index](http://doc.rust-lang.org/1.0.0-beta.4/std/#the-rust-prelude-and-macros) goes to an [empty page](http://doc.rust-lang.org/1.0.0-beta.4/std/macros/). Should this link to the [prelude docs](http://doc.rust-lang.org/1.0.0-beta.4/std/prelude/) instead? It looks like if you go there, the macros (like `println!`) are listed on the left sidebar.
