CodingGuidelines: spell out post-C89 rules

Even though we have been sticking to C89, there are a few handy
features we borrow from more recent C language in our codebase after
trying them in weather balloons and saw that nobody screamed.

Spell them out.

While at it, extend the existing variable declaration rule a bit to
read better with the newly spelled out rule for the for loop.
