Description
Some macros have match bodies inside, e.g. match_byte and match_ignore_ascii_case and the formatter skips those bodies.
Some of them are quite big, like here: src/tokenizer.rs:560

Research direction
Start with the match_byte and match_ignore_ascii_case macros, especially the example at src/tokenizer.rs:560, and run cargo fmt to reproduce the skipped formatting. Trace how these macro match bodies are represented and formatted; done means cargo fmt formats the bodies instead of leaving them unchanged.
