rustfmt is removing a static variable when max_width is set

[fitzgen]

Given this file:

input.rs:

extern "C" {
    #[link_name = "_ZN7MyClass26example_check_no_collisionE"]
 pub static mut  MyClass_example_check_no_collision  :  * const :: std :: os :: raw :: c_int ;
}

Running the most recently published rustfmt on it:

$ rustup run nightly rustfmt < input.rs > output.rs

Results in this file:

output.rs:

extern "C" {
    #[link_name = "_ZN7MyClass26example_check_no_collisionE"]
    ;
}

Note that the pub static mut MyClass_example_check_no_collision variable has disappeared and there is only a semicolon in its place.

The above only happens if I am running rustfmt inside a directory with the following rustfmt.toml:

max_width = 80

$ rustup run nightly rustfmt --version
0.2.2-nightly ( )
$ rustup run nightly rustc --version
rustc 1.21.0-nightly (469a6f9bd 2017-08-22)

I could not reproduce this with the latest master(0.2.2-nightly (1a02c35 2017-08-25)). It still exceeds max width, though.

My bad, I could.
