Yes, it did make it (abundantly, redundantly) clear. As it was already clear
from Stefan's earlier code-fragment post. And as it was clear to me from the
beginning, after looking at the code.
Not the question. What I was incorrectly supposing was that every character
code corresponded to either a non-empty name or a non-empty old-name. I did not
realize that both names might be empty.

Great. If they are all such, then I suppose we can in fact filter out all empty
entries.
