Not sure if "macro within macro" is the actual issue, but here's the example:

macro_rules! make_macro {
    ($d: tt $x: ident) => {
        macro_rules! make_x {
            ($d b: ident) => {
                pub struct $x{
                    pub $d b : (),
                }
            };
        }
    };
}

make_macro!($ Foo);

mod bar {
    make_x! {x}
}

fn main() {
    let _ = bar::Foo { x: () };
}

Rustfmt adds 2 indents on lines [4, 9] every time it's run.

Believe this is a duplicate of #4609?
