Tuples or methods with two `unsafe` blocks are ugly formatted

[sorairolake]

Tuples or methods with two unsafe blocks are formatted as follows:

let (n, m) = (unsafe { NonZeroU16::new_unchecked(u16::MAX) }, unsafe {
    NonZeroU16::new_unchecked(u16::MAX)
});

let r = NonZeroU16::div_ceil(unsafe { NonZeroU16::new_unchecked(u16::MAX) }, unsafe {
    NonZeroU16::new_unchecked(u16::MAX)
});

I think this is ugly.

Similar code without unsafe blocks would be formatted as follows:

let (n, m) = (
    NonZeroU16::new(u16::MAX).unwrap(),
    NonZeroU16::new(u16::MAX).unwrap(),
);

let r = NonZeroU16::div_ceil(
    NonZeroU16::new(u16::MAX).unwrap(),
    NonZeroU16::new(u16::MAX).unwrap(),
);

Similar to this, I think the first example should be formatted like this:

let (n, m) = (
    unsafe { NonZeroU16::new_unchecked(u16::MAX) },
    unsafe { NonZeroU16::new_unchecked(u16::MAX) },
);

let r = NonZeroU16::div_ceil(
    unsafe { NonZeroU16::new_unchecked(u16::MAX) },
    unsafe { NonZeroU16::new_unchecked(u16::MAX) },
);

I think this is a result of how Rust style rules around blocks work.

This can't be changed without another style edition, and personally I think this is niche enough that it doesn't matter. Might be a question for @rust-lang/style
