This is weird.

Weird or not, it's consistent with <domain-spec>.  And we can't 
change <domain-spec> _again_, the last AUTH48 mutilation was bad
enough.  I begin to hope that this change didn't break older SPF
implementations, AFAIK nobody reported problems with SPF policies
using the optional trailing dot in <domain-spec> so far.

Not all implementations support the trailing dot.  Libspf is at least one 
that does not.
