Summary

Implements the black remove_redundant_guard_parens and parens_for_long_if_clauses_in_case_block preview styles.

Black deviation

Like assignments, ruff prefers splitting the right side (if guard) over splitting the left (case).

Black

match 1:
    case (
        _
    ) if True:  # comment over the line limit and parens should go to next line
        pass

    case {
        "long_long_long_key": str(long_long_long_key)
    } if value := "long long long long long long long long long long long value":
        pass

Ruff

match 1:
    case _ if (
        True
    ):  # comment over the line limit and parens should go to next line
        pass

    case {"long_long_long_key": str(long_long_long_key)} if (
        value := "long long long long long long long long long long long value"
    ):
        pass

Test Plan

There are a few existing tests that cover this already nicely. I added a few new tests to ensure that comments are handled correctly.
