Condense `)\n.unwrap()` into a single line

eg it'd likely make sense for
```
        let data = Vec::<u8>::from_hex(
            "02020202020202020202 long line",
        )
        .unwrap();
```
to just be
```
        let data = Vec::<u8>::from_hex(
            "02020202020202020202 long line",
        ).unwrap();
```
at least for cases where the number of `)`s (and maybe `}`s) is under some threshold.
