Fix formatting issues with cargo fmt

[djc]

Noticed these unrelated formatting problems while working on #5258.

[matklad]

Hm, we run cargo fmt on CI, so I think this is how this is supposed to be formatted?

@djc how do you get rustfmt to use this other style? Perhaps you version of rustfmt differes?

[djc]

@matklad if you look at the failures in https://travis-ci.org/rust-lang/cargo/jobs/359754442, you see that they require these changes.

Figured out! We've released 1.25 today, which updated rustfmt as well.

Sorry for deleting this branch while the merge was still in progress. Does it need to be approved/triggered again to move forward?
