The pretty printer now correctly parenthesizes or-patterns inside `box` patterns, which changes the Clippy `unnested_or_patterns` lint suggestion from `box box (0 | 2 | 4)` to `box (box (0 | 2 | 4))`. The new output is more correct — the old suggestion was itself missing parens and would have been parsed as `box (box 0) | 2 | 4`. Signed-off-by: Andrew V. Teylu <andrew.teylu@vector.com>
