port maintainers not in contrib.additional.sgml

   By my count, there are 614 ports maintainers who are either not listed, 
or listed using a different email address, in 
doc/en_US.ISO8859-1/articles/contributors/contrib.additional.sgml.
   Would anyone object if I sent out a form letter to these apparently 
unlisted contributors, asking them if they'd like to be listed?  (And is 
someone willing to commit the resulting massive patch when I collect the 
replies together?)
