This is a spiritual succesor to rust-lang#34268/8531d581, in which we replaced a number of matches of None to the unit value with `if let` conditionals where it was judged that this made for clearer/simpler code (as would be recommended by Manishearth/rust-clippy's `single_match` lint). The same rationale applies to matches of None to the empty block.

In rust-lang#34268 (8531d58), we replaced matches of None to the unit value `()` with `if let`s in places where it was deemed that this made the code unambiguously clearer and more idiomatic. In rust-lang#34638 (d37edef), we did the same for matches of None to the empty block `{}`. A casual observer, upon seeing these commits fly by, might suppose that the matter was then settled, that no further pull requests on this utterly trivial point of style could or would be made. Unless ... It turns out that sometimes people write the empty block with a space in between the braces. Who knew?
