Not to mention all the root-server operators.  So the rule clearly
isn't being enforced very well. :)

Actually, to be lawyerly about it, while RFC952 says you can't have
a single-character name, it also defines names as including periods
to delimit domain-name components.  So, "" is really a
13-character name, with a single-character component at the beginning,
not a single-character name.
