Code from docs are ill-formatted

[kracekumar]

Clicking on the Run button from docs takes to play.rust-lang.org with the ill-formatted code snippet.

Here is how it looks

fn main() {
    let mut vec = Vec::new();
vec.push(1);
vec.push(2);

assert_eq!(vec.len(), 2);
assert_eq!(vec[0], 1);

assert_eq!(vec.pop(), Some(2));
assert_eq!(vec.len(), 1);

vec[0] = 7;
assert_eq!(vec[0], 7);

vec.extend([1, 2, 3].iter().cloned());

for x in &vec {
    println!("{}", x);
}
assert_eq!(vec, [7, 1, 2, 3]);
}

This is worse for fs:create_dir_all example.

fn main() {
    use std::fs;

fn foo() -> std::io::Result<()> {
try!(fs::create_dir_all("/some/dir"));
Ok(())
}
}

Link.

I am not sure the problem lies with generated docs or playground or with my browser/plugins.
