-    Function declarations follow the "Kernighan/Ritchie style". The function brace is on the same line as the function declaration. One space is required between the closing parenthesis and the brace.
+    The function opening brace must be on the same line as the function declaration, with exactly
+    one space between them, and must be the last content on the line.
