Disallow newline directly following `//` #1294

Currently this reference marks up e.g.

fn main() { //
    println!("Hello, world!");
}

as

fn main() { <comment-start>//
    println!("Hello, world!");<comment-end>
}

because the ~[/ !] rule allows a newline to sneak in before the ~\n*

Thanks for the PR! It looks like CI is a little broken. I posted rust-lang/rust#103952 which should fix it.

Thanks!
