Panic lint doesn't catch panics with formatting

[paulkernfeld]

It looks to me like the panic lint doesn't catch panics with formatting. Although maybe this is intentional, I would expect it to treat panics with and without formatting the same way.

I tried this code:

#[deny(clippy::panic)]
pub fn main() {
    panic!("{}", "This is a panic");
}

I expected to cargo clippy to fail on this code, but it passes.
