Thanks for the patch! The example results shown omit the backtrace for the cause of the exception, is that deliberate? Seems like it may be useful to show that --backtrace-limit affects the display of both the backtrace for the exception and it's cause.

Yes, it is: I wanted to make it shorter and easier to comprehend; but you are right, it makes more sense to show both. Updated (Though, TBH, in this particular case output of the cause seems more confusing than helpful: it is twice repeated error info with the same backtrace and error class, and only the message is different.)
