Browse source 
Improve the tuple and unit trait docs

* Reduce duplicate impls; show only the `(T,)` and include a sentence saying that there exists ones up to twelve of them.
* Show `Copy` and `Clone`.
* Show auto traits like `Send` and `Sync`, and blanket impls like `Any`.

Here's the new version:

* <https://notriddle.com/notriddle-rustdoc-test/std/primitive.tuple.html>
* <https://notriddle.com/notriddle-rustdoc-test/std/primitive.unit.html>
