nodes: expand/comment the magic nodes so they are more easily searchable
We just encountered `000000000000modified`, and it was quite annoying to search
for these, even though I knew they existed. For those that don't know that they
exist, this is essentially impossible to search for :)
(Technically we encountered it in its hex form,
3030303030303030303030306d6f646966696564, so I'm adding comments with those
forms in case that's helpful to people in the future).
