Comment after enum member prevents rustfmt from doing its work

[wooster0]

The following is not formatted by rustfmt due to the comment:

use std::cmp::Ordering;

fn main() {
    match 1.cmp(&1) {
        Ordering::Greater |
        Ordering::Equal //hello


        =>       {





                                          }
        
        _=> {}
    }
}

I expect a formatting like this:

use std::cmp::Ordering;

fn main() {
    match 1.cmp(&1) {
        Ordering::Greater |
        Ordering::Equal //hello
        => {}
        _ => {}
    }
}
