Subject: [PATCH] impl<T> Ranged for &T where T: Ranged (#16)

In the example below, `arg` is `&Expr`, so `&Ranged`, but `entries()`
want a `T: Ranged`. This adds the missing bridge impl.

```rust
        let all_args = format_with(|f| {
            f.join_comma_separated()
                .entries(
                    // We have the parentheses from the call so the arguments never need any
                    args.iter()
                        .map(|arg| (arg, arg.format().with_options(Parenthesize::Never))),
                )
                .nodes(keywords.iter())
                .finish()
        });
```
