#[display("{:?}")] could be better

#[derive(Display)]
#[display("{:?}")]
enum E {
    A,
    B,
}

It generates the following Display::fmt:

match self {
    &Self::A=> f.write_fmt(format_args!("{0:?}", "A")),
    &Self::B=> f.write_fmt(format_args!("{0:?}", "B")),
}

I think "{:?}" should generate the following:

<Self as Debug>::fmt(self, f)

That's a good idea.

Indeed, there's no need to make traits other than Display available for variant names, and it would be convenient if formatting traits for Self could be made available.

I implemented this specification with de8a9431787053078ed706fc6ff53126c35a4acf.

There are some inefficiencies in the generated code, which I will eventually fix.

Thank you.
