Currently it only tests AST pretty-printing. This commit changes it to run every example through both AST pretty-printing and TokenStream pretty-printing. This makes it clear where there two pretty-printing approaches produce different results.

By adding tests (or placeholders, or comments) for missing AST variants.

By making some case more complex, adding some new cases, tweaking formatting, and removing unnecessary `rustfmt` attributes.
