Rustdoc has broken HTML for deprecation reasons

[Manishearth]

See http://doc.rust-lang.org/core/marker/index.html

Structs

• `'>ContravariantLifetime Old-style marker trait. Deprecated.
• ContravariantType Old-style marker trait. Deprecated.
• `'>CovariantLifetime Old-style marker trait. Deprecated.
• CovariantType Old-style marker trait. Deprecated.

• `'>InvariantLifetime Old-style marker trait. Deprecated.

It seems like the PhantomData<&'a ()> from the deprecation reason is being treated like HTML and causing some extra close angle brackets to appear.
