Drop the standalone formatting-only change

This commit only reflows an existing comment and makes no behavioral change, so as a standalone contribution it is exactly the one-off mechanical cleanup that the repository requires contributors not to submit; bundle it with substantive work instead of proceeding with this change alone.
