Matthias Krüger a8f8f746fc Rollup merge of #91437 - dtolnay:emptybrace, r=nagisa ... Pretty print empty blocks as {} **Example:** ```rust macro_rules! p { ($e:expr) => { println!("{}", stringify!($e)); }; ($i:item) => { println!("{}", stringify!($i)); }; } fn main() { p!(if true {}); p!(struct S {}); } ``` **Before:** ```console if true { } struct S { } ``` **After:** ```console if true {} struct S {} ``` This affects [`dbg!`](https://doc.rust-lang.org/std/macro.dbg.html), as well as ecosystem uses of stringify such as in [`anyhow::ensure!`](https://docs.rs/anyhow/1/anyhow/macro.ensure.html). Printing a `{ }` in today's heavily rustfmt'd world comes out looking jarring/sloppy.		2021-12-05 15:04:20 +01:00
