needless_doctest_main reports wrong line if there are imports

fn main() {
    println!("Hello, world!");
}

It looks like the lint assumes the fn main() will always be in the first line of the code block..?

warning: needless `fn main` in doctest

  = note: `#[warn(clippy::needless_doctest_main)]` on by default

This causes strange looking warnings.
