Description
quote! is fairly popular for code generation, and more often than not its argument could be passed and formatted as valid Rust code.
The only thing that prevents that from happening right now is parser stumbling on #name substitutions, but if they're temporarily replaced with regular identifiers as we already do for macro definitions, this shouldn't be a problem.

Research direction
Start by tracing how rustfmt parses quote! arguments and how macro definitions temporarily replace substitutions such as #name. Confirm the parser failure with representative valid Rust code, then verify that quote! arguments containing these substitutions are formatted successfully without changing their meaning.
