Empty comment before match causes parse error

[dafaust]

I tried this code:

fn foo (x: i8) -> i32 {
    //
    match x {
        1 => { return 1; }
        _ => { return 0; }
    }
}

I expected to see this happen: Compiles without error.

Instead, this happened:

bug.rs:3:11: error: expecting ‘}’ but ‘=>’ found
    3 |     match x {
      |           ^
bug.rs:3:11: error: error may be from having an expression (as opposed to statement) in the body of the function but not last
bug.rs:6:1: error: unrecognised token ‘}’ for start of item
    6 |     }
      | ^
bug.rs:6:1: error: failed to parse item in crate

Compiles fine without the empty comment line.
