Generator functions aren't formatted in a sane manner. Here's an example of how an anonymous generator function would be formatted with the current formatting rules:

-    docs: function *() {
-           for (let i = 0; i < 100; i++) {
-               yield {};
-           }
-    },
+    docs: function *
+        () {
+            for (let i = 0; i < 100; i++) {
+                yield{};
+            }
+        },

Specifically, I'm requesting that both the asterisk/newline spacing be fixed to one line, and another space added between the yield keyword and the subsequent expression.
