Issue: "help: remove the extra argument" prints too much of the function arguments
Labels: A-diagnostics,T-compiler,A-suggestion-diagnostics,D-verbose

Given the following code: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=d6dfe3d605639255444883813f8376db

```rust
enum CargoMessage {
    CompilerArtifact {
        filenames: Vec<String>,
        target: CargoTarget,
        extra: bool,
    }
}

struct CargoTarget {
    crate_types: Vec<String>,
}

pub fn run_cargo() {
    let is_debug_info = |_| true;
    let is_dylib = |_| true;
    let is_check = true;
    let ok = stream_cargo(vec![], &mut |msg| {
        let (filenames, crate_types) = match msg {
            CargoMessage::CompilerArtifact {
                filenames,
                target: CargoTarget { crate_types },
                ..
            } => (filenames, crate_types),
            _ => return,
        };
        for filename in filenames {
            // Skip files like executables
            if !(filename.ends_with(".rlib")
                || filename.ends_with(".lib")
                || filename.ends_with(".a")
                || is_debug_info(&filename)
                || is_dylib(&filename)
                || (is_check && filename.ends_with(".rmeta")))
            {
                continue;
            }
        }
    });
}

pub fn stream_cargo(
    cb: &mut dyn FnMut(CargoMessage),
) -> bool {
  true
}
```

The current output is:

Ideally the output should look like:

Printing the entire body of the closure is ... a bit much :laughing:
