Block comment bug

[Vinatorul]

Single-line block comment counts erroneously. For this sample

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

I got

         Language  Files  Lines  Blanks  Comments  Code  Unsafe (%)
         --------  -----  -----  ------  --------  ----  ----------
         Rust      1      4      0       4         0     0 (NaN%)
