 ### Pretty multiline variable declaration
 
 In the original mode,
 
-    var foo = 10,
-    bar = 20,
-    baz = 30;
+```js
+var foo = 10,
+bar = 20,

-    let {a: a, b: b} = {a: 10, b: 20}; // Same as above (Supported in the original mode)

 ### Fix for odd indentation of "else if" with no braces

-    return bar;      // here

 ### Imenu support for function nesting
 
 Supports function nesting and anonymous wrappers:
 
-    (function() {
-      var foo = function() {
-        function bar() { // shown as foo.bar.<definition-1>
-          function baz() {} // foo.bar.baz
-          var qux = function() {}; // foo.bar.quux
-        }
-      };
-    });
+```js
+(function() {
+  var foo = function() {
+    function bar() { // shown as foo.bar.<definition-1>
+      function baz() {} // foo.bar.baz
+      var qux = function() {}; // foo.bar.quux
