In fact, Joe, I think it's distinguishing your second case from "a label
string which is intended to reference a rooted FQDN, but the user did not
specify the trailing dot -- and yet still does not want a search path 
applied"...

which is 99.9999% of the time outside of large corporate and college
campuses, and only 99.9% of the time, otherwise.  :-)

No, what's *really* unhelpful and misleading is the people who say that
it is the *dot* which specifies the name of the root, rather than the
null labelstring which *follows* that dot (which is what it actually
is, and I'll save everyone's stomach linings by not saying the words
"alternate root" here. :-)
