rustfmt removes oddly placed comments

[zacheryph]

rustfmt likes to remove commented lines that are found in odd places. This appears to affect both stable and nightly rustfmt.

Input File

struct X<T>
// where
//     T: Clone
{
    inner: String,
}

After rustfmt

struct X<T> {
    inner: String,
}
