Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
This file has been created prior to CVS rev 1. Instead of listing all
the years since 1999, I just put 1999, 2010 and 2011.
