The variable newinet is initialized twice to the same (side effect-free)
expression. Drop one initialization.
A simplified version of the semantic match that finds this problem is:

Julia, just like patch #3 this one had the missing final
line of the patch corrupting it, so you'll need to resubmit.

I have generated and sent it again, but this time I don't see the problem.
If there is still a problem, perhaps you could send me back the patch you
received?

You dropped Vlad' ACK in your re-submission.
I'll fix it up this time, but please accumulate ACK's when
resubmitting patches merely for the purpose of fixing some
technical submission problem.
Thanks.
