incorrect indent for dbg!(tiny_vec)

[kzhui125]

use tinyvec::tiny_vec;

#[derive(Debug)]
pub struct Point {
    id1: i32,
}

impl Default for Point {
    fn default() -> Self {
        Self { id1: 0 }
    }
}

fn main() {
    let arr = tiny_vec!([Point; 1] => Point { id1: 1 });
    dbg!(arr);

    let arr = vec![Point { id1: 1 }];
    dbg!(arr);
}

let arr: TinyVec<[char; 10]> = tiny_vec!();
dbg!(arr);
let arr: Vec<char> = vec![];
dbg!(arr);

We changed from using arrayvec::ArrayVec to tinyvec::ArrayVec in our project and some checked-in insta tests ended up changing because of this. This just seems like a bug...

fwiw in arrayvec it just makes a slice and uses its Debug. I'm not sure why tinyvec is doing all this manual stuff with iterating elements etc: just get the slice and format it? This seems the most intuitive and correct.

Yeah it's fair to say this is a bug.

Feel free to PR the fix, or I can try to find some time this week maybe.

[Fuuzetsu]

I'll send something in.

I guess we can improve the Display instance in the same way: you can't just Display slices because the impl doesn't exist but we could do a small trick where we use the Debug instance but we wrap the inner T so that the Debug uses the Display. A stretch goal for sure, I think just fixing Debug probably scratches the itch for 99% of the use-cases: people just using normal slices/arrays didn't have the Display to start with after all.
