Changelog for optional vectors may have wrong example for old behaviour

[AluisioASG]

From the changelog; issue in comments:

If you need to fall back to the old behavior you can use a type alias:

type Something = Vec<String>; // Not actually used
#[derive(StructOpt)]
struct Opt {
  #[structopt(long)]
  fruit: Option<Vec<String>>, // Shouldn't this be `Option<Something>`?
}

That's right, thanks for reporting
