Yeah, I considered that, but I rejected the idea on the grounds that all
the preceding blocks use this style. (Also, if I understand you well,
what you suggest would incur into a translatability problem; we'd have
to create two separate messages for that purpose anyway.)

Well, as Dean points out, as soon as we have NOT VALID constraints it
will be necessary. I prefer to leave that out for a later patch.
Thanks for looking.
