RE: [hobbit] Issues with NCV

[Tom Moore <Tom.Moore (at) sas.com>]

I already had a newline at the end.  And I did the swapping as well.  What's strange is I threw a random line at the end

Blah: 20

And now I get 4 results instead of 5.

So it seems to always ignore the last name comma value in the set.. very strange.

IIRC correctly, you need a newline at the end of the last one.

If that's not that case, then try swapping the last one and third one
around in an effort to troubleshoot - it may be that the 4th has some
misconfiguration or something.
