Format core and std macro rules, removing needless surrounding blocks Many of the asserting and printing macros in `core` and `std` are written with prehistoric-looking formatting, like this: https://github.com/rust-lang/rust/blob/335ffbfa547df94ac236f5c56130cecf99c8d82b/library/std/src/macros.rs#L96-L101 In modern Rust style this would conventionally be written as follows instead, always using braces and a trailing semicolon on the macro arms: https://github.com/rust-lang/rust/blob/af53809c874e0afb7be966df4d3cfcaa05277c53/library/std/src/macros.rs#L98-L105 Getting rid of the unneeded braces inside the expansion reduces extraneous indentation in macro-expanded code. For example: ```rust println!("repro {}", true); ``` ```rust // before: { ::std::io::_print( ::core::fmt::Arguments::new_v1( &["repro ", "\n"], &[::core::fmt::ArgumentV1::new_display(&true)], ), ); }; ``` ```rust // after: ::std::io::_print( ::core::fmt::Arguments::new_v1( &["repro ", "\n"], &[::core::fmt::ArgumentV1::new_display(&true)], ), ); ```
