Re: [ddlm-group] Close quotes not followed by whitespace

Dear Colleagues,

   Please do not misunderstand my position.  I recognize that I cannot
win on the issue of the handling of the reverse solidus in CIF2, and
believe we should move on.  That does not mean that I think that
this is a sound decision for the future of CIF2, just that it is
the COMCIFS decision for the definition of CIF2.  We have other
issues to discuss.

   Regards,
     Herbert
