   For example, given the following original document:
 
   {
-    a = "b";
-    c = {
+  a = "b";
+  c = {
       d = "e";
       f = "g";
-    }
+  }
   }
 
   Changing the value of `a` and removing `f` can be achieved by merging the patch
 
   {
-    a = "z";
-    c.f = null;
+  a = "z";
+  c.f = null;
   }
 
   which results in
