Re: copyrights to be fixed

[Chong Yidong]

The smiley images are from Gnus.  From looking at the Gnus ChangeLog,
it seems that the smilies are authored by various people, who have FSF
copyright assignments in place:

Reiner Steib
Simon Josefsson
Kai Grossjohann
Alex Schroeder
Oliver Scholz
Per Abrahamsen
Kim F. Storm

I will create a README file crediting these folks and stating (C) FSF.
Let's then treat the etc/images/smilies issue as resolved.  After all,
it takes about half a minute to create each of these little images;
let's not lose any sleep over them.
