   A minor point:

   The most-recent copyright holder should come first.
   This is the typical usage.  It is more convenient
   for the reader, who typically is interested in the
   most recent-changes first.  Sort of like a ChangeLog.

   I updated the wiki accordingly.

M-x copyright-update prefers it as well, in the above it would add
2014 to the 2010 line.
