Re: CIF line limits

Dear Gotzon,

	Thank you for your comments which strongly support the position
that Herbert Bernstein has been promoting.  Herbert, Brian and I have been
working on a formal proposal which we hope (when it is ready) to present
to Comcifs.  The essence of this proposal will be a line limit of around
2000 characters for CIF 2.0 but with a strong recommendation that people
should continue to observe the 80 character line limit of CIF 1.1 wherever
possible.  The proposal contains a mechanism by which a file written in
CIF 2.0 can, if necessary, be folded into 80 characters in such a way that
it can be fully reconstructed with long lines later.  It may be a week or
two before this proposal is ready to be presented, but we are actively
working on it.
