rustfmt fails when encountering comment (+ trailing whitespace)

[lesurp]

⮞ cargo fmt --version
rustfmt 1.4.4-stable (0462008 2019-08-06)

No trailing whitespace

fn main() {
    let a =
            // asasddasas 
    if true {
     1.0
    };
}

output: exact same (the 1.0 line is not indented

With trailing whitespace:

Please note the trailing whitespace after the let a= line

fn main() {
    let a = 
            // asasddasas 
    if true {
     1.0
    };
}

output:

 ⮞ cargo fmt
error[internal]: left behind trailing whitespace
 --> /tmp/foo/src/main.rs:2:2:11

Thanks for the report @lesurp. I forget which version of rustfmt contains the fix for this (I want to say 1.4.6 or 1.4.7), but it has already been fixed.

If you try your snippet with the latest nightly version of rustfmt (1.4.9) you'll see the snippet correctly formatted without error

Oops, I was wrong sorry (my editor was trimming the trailing whitespace). I can reproduce this with the latest 1.4.9
