rustdoc doc for deprecated doesn't contain hint about what use instead

[Dushistov]

Look for example to bindgen hide_type method

It is deprecated, and in source code there is hint what should be used instead:

/// Hide the given type from the generated bindings. Regular expressions are
    /// supported.
    #[deprecated = "Use blacklist_type instead"]
    pub fn hide_type<T: AsRef<str>>(self, arg: T) -> Builder {
        self.blacklist_type(arg)
    }

but in generated html documentation there is no hint about Use blacklist_type instead

#[deprecated = "Use blacklist_type instead"] isn't the correct syntax for the #[deprecated] attribute. It should be #[deprecated(note = "Use blacklist_type instead")]. You can see it work: unstable_rust src.

This isn't a rustdoc issue. It's an issue with rustc that it doesn't reject #[deprecated = "Use blacklist_type instead"].
