New option proposal for `requireObjectKeysOnNewLine`

Per https://github.com/eslint/eslint/issues/5667#issuecomment-219334864

The JSCS rule requireObjectKeysOnNewLine had an allExcept: ['sameLine'] option, that eslint currently lacks. The idea was to configure it so that the following code warned:

var obj = {
  foo: "foo", bar: "bar", baz: "baz"
};
var obj = {
  foo: "foo", bar: "bar",
  baz: "baz" };
var obj = {
  foo: "foo", bar: "bar",
  baz: "baz"
};
var obj = { foo: "foo",
  bar: "bar",
  baz: "baz"
};

and only the following did not:

var obj = { foo: "foo", bar: "bar", baz: "baz" };
var obj = {
  foo: "foo",
  bar: "bar",
  baz: "baz"
};

The allowMultiplePropertiesPerLine isn’t quite the same thing. Can an option be added to support this behavior from jscs?

I’m seeing a separate rule for line breaks inside braces: https://github.com/eslint/eslint/issues/6072

Thanks for clarifying - in that case, I misunderstood the previous jscs behavior to be sufficient for my use cases. New option it is!
