This involves replacing `nt_pretty_printing_compatibility_hack` with `stream_pretty_printing_compatibility_hack`. The handling of statements in `transcribe` is slightly different to other nonterminal kinds, due to the lack of `from_ast` implementation for empty statements. Notable test changes: - `tests/ui/proc-macro/expand-to-derive.rs`: the diff looks large but the only difference is the insertion of a single invisible-delimited group around a metavar.
