Avoid double indentation when unnecessary

[ego-thales]

Hello,

I'd like your opinion on black's handling of the following case and what I think would be preferable

# Original
A = func([fooooooooooooooooooooooooooooooooooooooo for bar in baaaaaaaaaaaaaaaaaaaaaaaaaaaaaz])

# Current black
A = func(
    [
        fooooooooooooooooooooooooooooooooooooooo
        for bar in baaaaaaaaaaaaaaaaaaaaaaaaaaaaaz
    ]
)

# Preferred
A = func([
    fooooooooooooooooooooooooooooooooooooooo
    for bar in baaaaaaaaaaaaaaaaaaaaaaaaaaaaaz
])

Do you think it would be reasonable to hope for in future developments of black?

Thanks for your time.

This is already in the unstable style, as documented at https://black.readthedocs.io/en/stable/the_black_code_style/future_style.html#labels-hug-parens . However, we can't stabilize this until a number of issues and crashes have been fixed (#4036, #4098, #4099).
