I've committed a patch that improves the handling of cs_precedes,
sign_posn et al.  I don't agree with your proposal to slavishly follow
the locale definition no matter how brain-dead it is, because that would
destroy the ability to dump and reload data without data loss --- for
example, if we obeyed an empty negative_sign setting, we'd lose the
information that a value had been negative.  AFAICT there are no such
locales anyway, other than POSIX for which we definitely don't want to
believe the empty-string setting.
