unnecessary_to_owned suggestion cause error when interacting with println! macro

[GitPinkRabbit]

Summary

Clippy thinks the left curly bracket { in println!("{c}") is an &.

Lint Name

unnecessary_to_owned

Reproducer

I tried this code:

fn main() {
    let v: Vec<_> = "hello".chars().collect();
    for c in v.iter().cloned() {
        println!("{c}");
    }
}

I saw this happen:

warning: unnecessary use of `cloned`
 --> src\main.rs:3:14
  |
3 |     for c in v.iter().cloned() {
  |              ^^^^^^^^^^^^^^^^^
  |
  = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#unnecessary_to_owned
  = note: `#[warn(clippy::unnecessary_to_owned)]` on by default
help: use
  |
3 |     for c in v.iter() {
  |              ~~~~~~~~
help: remove this `&`
  |
4 -         println!("{c}");
4 +         println!("c}");
  |

I expected to see this happen:

Do not suggest to remove the &.
