You could argue the existing rule already covers these cases by
excluding selection and iteration statements from the "single statement"
in "Do not unnecessarily use braces where a single statement will do."
Define "statement"? There's a school of thought that uses semicolons to
indicate a statement. I'm trying to eliminate any ambiguity by calling
out compound statements as "more than one statement". Sure, semantics,
but in the interest of clarity. An additional sentence and example
doesn't really cost much.
Thank you for your time. I've made some changes, and a v2 to follow shortly.
