Hi Jelte! I have to get used to your (new?) email address!

Ok, on trailing garbage, this is rife on the internet. PowerDNS used
to error out on it, but it was not doable.

So now we ignore it, and life is good.

What is right for ldns depends on your goals, but if you want to make
ldns suitable as a base to build 'real life' solutions on, you almost
have no choice beyond ignoring trailing garbage on otherwise valid
