I don't know dg_script well at all, so I could be mistaken.
But, I think these are just minor errors in this script.
I have a separately-implemented mud codebase that interprets the
worlds from tbamud, and it flags these as errors, and some other
issues I might chose to fix later, depending on how this PR goes. :)
Of course, it's possible this is really a bug in my own codebase, and
not in these scripts... but I don't think so - and the documentation
I've managed to find seems to confirm my suspicion.
