Commented Unassigned: Enter after unmatched curly brace causes exception [1386]

Hi,

Whenever I press enter after an unmatched opening curly brace I get an "Object reference not set to an instance of an object" error prompt.

Whenever I press enter after an unmatched closing curly brace I get an "Count must be positive and count must refer to a location within the string/array/collectionudio. Parameter name: count." error prompt.

For instance:

```
var func = function () {<enter here causes a "Object reference not set to an instance of an object>
```

Here's my setup:
Microsoft Visual Studio Professional 2013
Version 12.0.30723.00 Update 3
Node.js Tools 1.0.20905.00
Node.js Tools - Profiling 1.0.20905.00

Thanks
