rustfmt not remove extra blank lines on top of the file and on the middle of the functions

[dumindu]

Current

use std::fs::File;
use std::io::Read;

fn main() {
    let mut file = File::open("src/hello.txt").expect("file not found");
    let mut content = String::new();
    file.read_to_string(&mut content)
        .expect("can't read the file");



    println!("{}", content);
}

Expected

use std::fs::File;
use std::io::Read;

fn main() {
    let mut file = File::open("src/hello.txt").expect("file not found");
    let mut content = String::new();
    file.read_to_string(&mut content)
        .expect("can't read the file");
    
    println!("{}", content);
}

This is actually one of the oldest issues with Rustfmt. It was deliberate at the time, but I think we should fix this now. I believe we defined the desired behviour in the formatting RFCs.
