Struct field patterns with `cfg`s are formatted unlike anything else

[kpreid]

Using rustfmt 1.6.0-stable (2023-12-04 a28077b), the following formatting is produced:

struct Foo {
    #[cfg(all())]
    something_long_enough_to_wrap_foo: i32,
    #[cfg(all())]
    something_long_enough_to_wrap_bar: i32,
}

fn example() {
    let Foo {
        #[cfg(all())]
        something_long_enough_to_wrap_foo,
        #[cfg(all())]
            something_long_enough_to_wrap_bar: bar_var,
    } = Foo {
        #[cfg(all())]
        something_long_enough_to_wrap_foo: 111,
        #[cfg(all())]
        something_long_enough_to_wrap_bar: 222,
    };
}

Note that in the Foo pattern, the line something_long_enough_to_wrap_bar: bar_var is indented one more level, but in all other cases, there is no additional indentation level. This seems unusual and inconsistent, and so I suggest that it be changed to be consistent in the next "style edition".

Thanks for the report! This is definitely an odd case. This issue came to mind since they both have to do with patterns. I wonder if they're somehow related #5117 🤔
