@stvstnfrd to review commit
As much as I love reformatting code for aesthetics (no, seriously... I
do), our general rule is to avoid making these changes _directly
alongside_ functional changes.  So for whitespace/formatting changes
without logic/function changes, these should _at least_ be introduced in
a separate commit or even a separate pull request entirely.

This makes it much easier to determine at a glance what changed in a
specific commit/merge. Also, making strictly aesthetic changes muddies
the `git blame/log` for that line/file, making it more difficult to
track down authors and changes in the future.

While I agree that this change _is_ an improvement, I'd suggest
reverting this change from this commit.
