Coding Standards: Require blank line between function definitions

I propose that a coding standard be to require a blank line between function definitions. That is, instead of:

function foo() {
  return 'baz';
}
function bar() {
  return 'baz';
}

You would have:

function foo() {
  return 'baz';
}

function bar() {
  return 'baz';
}

(I am reporting this minor feature request via the issue queue because I could not find a way to edit the Coding Standards page.)
