Conditionals in function arguments with question mark

[Gama11]

The formatter handles conditionals in function arguments pretty well:

class Main {
	static function foo(#if false bar:Int, #end foobar:Int) {}
}

However, if the second argument here starts with a ?, the space after #end goes missing:

class Main {
	static function foo(#if false bar:Int, #end?foobar:Int) {}
}
