Confusing error message for `async move` in the 2015 edition

[goffrie]

Playground:

fn main() {
    async move { };
}

yields this error:

error: expected one of `!`, `.`, `::`, `;`, `?`, `{`, `}`, or an operator, found keyword `move`
 --> src/main.rs:2:11
  |
2 |     async move { };
  |           ^^^^ expected one of 8 possible tokens

#71783 added a hint about the edition for async {}, but it seems that async move {} doesn't get it.

Output on rustc 1.79.0

error: `async move` blocks are only allowed in Rust 2018 or later

2 |     async move { };
  |     ^^^^^^^^^^

error: aborting due to 1 previous error

I agree, this looks fixed.
