VS2013 only.
I was typing a for loop in the REPL while debugging:
```
for (var i = 0; i < 5; i++) { }
```
and I hit enter after typing the open brace (the close brace appeared automatically).
I got a msgbox with the activity log path. Here's the callstack from the activity log:
```
System.NullReferenceException: Object reference not set to an instance of an object. at Microsoft.VisualStudio.JSLS.BraceCompletion.FormatOnEnterBraceCompletionContext.ShouldFormatOnEnter() at Microsoft.VisualStudio.JSLS.BraceCompletion.FormatOnEnterBraceCompletionContext.OnReturn(IBraceCompletionSession session) at Microsoft.VisualStudio.Text.BraceCompletion.Implementation.BraceCompletionDefaultSession.PostReturn() at Microsoft.VisualStudio.Text.BraceCompletion.Implementation.BraceCompletionManager.<PostReturn>b__25() at Microsoft.VisualStudio.Text.Utilities.GuardedOperations.CallExtensionPoint(Object errorSource, Action call)
