Update C++ style guide:

- Allow unsigned types where defined overflow behavior is desired
 - Clarify that a function-closing } is permitted on the same line as an
   opening { for one-line functions

           You should not use the unsigned integer types such as
           <code>uint32_t</code>,
           unless the quantity you are representing is really a bit pattern
-          rather than a number. In particular, do not use unsigned types to
-          say a number will never be negative.  Instead, use
+          rather than a number, or unless you need defined

           assertions for this.
