R is already ?Sized. What does this change?

@workingjubilee previously peek was in an impl block that was not ?Sized (the same one as new and with_capacity). it should be in a block with the same bounds as BufRead.

namely, this code should run now:

#![feature(bufreader_peek)]

use std::io::{Read, BufReader, stdin};

fn main() {
    let r1 = BufReader::new(stdin());
    let r2: Box<BufReader<dyn Read>> = Box::new(r1);
    println!("{:?}", r2.peek());
}

OH, I see the block change now.
