DoF posting--copyright correction

[Martin Taylor 920701]

Bill Cunningham brought to my notice that the copyright wording I added to
my long posting of 2:40 this morning could be interpreted as prohibiting
copying the message to interested parties outside CSG-L. That was not my
intent. I added the notice because I had an idea that some refined version
of the posting might one day become a paper, and some journals have strong
views on prior publication. Accordingly, I should like to amend the
copyright notice so as to permit personal circulation but not public
dissemination outside CSG-L. I might ask that anyone who does circulate
it personally let me know, and if possible that they might pass back comments
they might receive on it.
