rustfmt keeps indenting macros ofter each run

Original source

mod x {
    quickcheck! {
        fn test(a: String, s: String, b: String) -> TestResult {
            if a.find(&s).is_none() {

                TestResult::from_bool(true)
            } else {
                TestResult::discard()
            }
        }
    }
}

1 run

mod x {
    quickcheck! {
            fn test(a: String, s: String, b: String) -> TestResult {
                if a.find(&s).is_none() {
    
                    TestResult::from_bool(true)
                } else {
                    TestResult::discard()
                }
            }
        }
}

2 runs

mod x {
    quickcheck! {
                fn test(a: String, s: String, b: String) -> TestResult {
                    if a.find(&s).is_none() {
    
                        TestResult::from_bool(true)
                    } else {
                        TestResult::discard()
                    }
                }
            }
}

Version

0.2.2-nightly ( )

Minimizing further seems to make rustfmt leave the macro alone.

#1907 might be the cause?

This is definitely introduced by #1907. Looks like we get this behavior when we have an empty line inside block.
