Re: [ddlm-group] Space as a list item separator

That was added precisely to _allow_ the bracketed constructs (which
at that time were intented all to be carried by []) to have a
non-conflicting place in a CIF.  Most cif parsers know nothing about
that restriction and would just carry [1,2,3] as an ordinary non-delimited 
string.
