bug in hash example: hash call not skipped

The output of hash.expand.rs has this:

impl Hash for DataType
where
    u8: Hash,
{
    fn hash<H: Hasher>(&self, state: &mut H) {
        self.foo.hash(state);
        self.bar.hash(state);
    }
}

That's surprising, since the input has this:

    #[adhoc(hash(skip))]
    bar: Vec<String>,

Did we make a mistake in the definition of MyHash? Should fmeta(hash::skip) be fmeta(hash(skip))?
