By looking whether there's at least one dot in the name.  I think
resolvers used to behave like this back some time ago.  So,

	x

would only be tried as

	x.search.domain1  x.search.domain2

and then given up, while

	x.foo

would be tried as

	x.foo.search.domain1 x.foo.search.domain2 x.foo

I think this is reasonable since there are no A/MX/CNAME records to be
expected for a TLD (i.e. a TLD is always only be used as part of the
recursion), so it could be special-cased.
