Subject: [PATCH] Document rustfmt on nightly-rustc

The recursion_limit attribute avoids the following error:

```
error[E0275]: overflow evaluating the requirement `std::ptr::Unique<rustc_ast::Pat>: std::marker::Send`
  |
  = help: consider adding a `#![recursion_limit="256"]` attribute to your crate (`rustfmt_nightly`)
```
