Short code listings don't display Ferris

[MichaelBlume]

Listing is

fn main() {
    panic!("crash and burn");
}

which definitely panics. Source in book is

<please imagine a triple-quote here which I don't know how to escape>rust,should_panic,panics
{{#rustdoc_include ../listings/ch09-error-handling/no-listing-01-panic/src/main.rs}}
<another triple-quote>

which looks like it's meant to display the panic icon? But in my browser it displays as

with no panicking Ferris.

Triage: the reason that this doesn't show ferris is that in ferris.js, we only attach a ferris to samples that have four lines or more. This is because ferris is too big for this box.

I am not sure what to do here. Smaller ferrises feel worse, imho. adding a blank newline here would be less than ideal, because it would also look weird. maybe a comment?

Maybe Ferris could be before the box? Not sure. Changing the issue to reflect the more general problem.
