regression(?): Pretty debug printing now strips hyphens

[bergmark]

What happened?
When upgrading from uuid 0.8 to 1.2 pretty-debug-printing changed to not contain hyphens

Steps to reproduce the behavior:

fn main() {
    println!("{}", uuid::uuid!("161d93bd-bd16-4c9c-b236-2e044546f36c"));
    println!("{:?}", uuid::uuid!("161d93bd-bd16-4c9c-b236-2e044546f36c"));
    println!("{:#?}", uuid::uuid!("161d93bd-bd16-4c9c-b236-2e044546f36c"));
}
