Missing documentation when re-exporting enumeration variants

[IvanUkhov]

When a private child module defines an enum and pub-uses its variants, and the parent module re-exports the content of the child module:

mod foo {
    pub enum Foo {
        Bar,
    }
    pub use self::Foo::*;
}

pub use self::foo::*;

it is not visible in the documentation of the parent module that the variants of the enum are directly accessible to the user. However, if the child module was public, the pub-use of the variants would be shown on the pages of both modules.
