In the hopes of soon having the benchmark code linted, this change groups all the likely non-controversial lint-compliance changes such as indentation, semi-colon usage, and single-vs.-double quotation marks. Other lint rules may have subtle performance implications in the V8 currently shipped with Node.js. Those changes will require more careful review and will be in a separate change.

// When calling .end(buffer) right away, this triggers a "hot path"

// However, the overhead of copying a large buffer is higher than

// the overhead of an extra write() call, so the hot path was not
