nextstep copyright issues

[Glenn Morris]

At first glance, the following people listed in nextstep/AUTHORS do
not have copyright assignments (I could just be not seeing them):

Michael Brouwer  "NEEDS DISCLAIMER BEFORE NEW CONTRIBUTIONS ACCEPTED?"
                 (probably OK...)
Christian Limpach (only gnus)
Christophe de Dinechin

These contributions sound like they might be tiny:

Scott Byer (only gnus)
Scott Hess
Rahul Abrol
Adam Ratcliffe
David M. Cooke
Carsten Bormann
Andrew Moore

And none of the "GNUstep port" people (probably no code).


doc/emacs/ns-emacs.texi needs the copyright holders (but see above)
and license fixing.  It also lists some people not in
nextstep/AUTHORS without assignment: Leigh Smith, Steve Nygard.
(probably this should all be merged and moved into AUTHORS).


nextstep/GNUstep/Emacs.base/Resource/emacs.tiff should have a README
like those in etc/images.  (Does this file need to be here rather than
in etc/images?)
