Whitespaces in path to macro inside derive block

[kuqmua]

"cargo fmt" command does not remove white spaces in derive block. For example i expected this

#[derive(serde :: Serialize)]
enum Something {
    Variant
}

to become this

#[derive(serde::Serialize)]
enum Something {
    Variant
}

cannot find anything similar in https://rust-lang.github.io/rustfmt/?version=master&search= tried to find by words "space" or "derive" (default config)

@kuqmua thanks for the report. What version of rustfmt were you using? You can find this out by running rustfmt --version.
