In general, we strongly discourage the use of pseudonymous copyright holders. 
Use the legal names of holders wherever possible.  Having as few copies of 
$hashalgorithm as possible also an excellent idea.

(Agreed that the public domain is problematic due to differing notions of 
public domain in different jurisdictions.  Our preferred reference license 
remains in /usr/share/examples/etc/bsd-style-copyright; it's ideal if patches 
come with that pre-attached by the author.)
