C400 unsafe fix is more unsafe than the documentation suggests

The C400 unsafe fix says that that it sometimes drops comments. It may also generate broken code:

ruff check fix --unsafe-fixes --select C400

list(
    (1 for _ in range(1))
)

expected

[
    1 for _ in range(1)
]  # [1]

actual

[
    (1 for _ in range(1))
]  # [<generator object <genexpr> at ...>

👍 Yeah that's a bug (rather than a question of fix safety). Thanks.
