+            // if you have smart-indentation on and are just hitting enter, you'll common have the
+            // caret placed one indent higher than your current construct.  For example, if you have:
+            //
+            //      if (true)
+            //          $ <-- smart indent will have placed the caret here here.

+            // This is acceptable given that the user may want to just write a simple statement there.
+            // However, if they start writing `{`, then things should snap over to be:

+            //      if (true)
+            //      {

+            // Importantly, this is just an indentation change, no actual 'formatting' is done.  We do

+            //
+            // If the user hits `}` then we will properly smart indent the `}` to match the `{`.
