	Close... There was a previous thread on this that culminated in a
post by Charles Levert: http://radscan.com/nas/nas-ml/msg00348.html.  

	Basically, it's the fact that au format is the first in the list
of openFile hooks that are tried in order to determine the right format of
the data. The first one (au) wins if it matches, so no fseeks are done in
the following hooks.

	This would be a good thing to properly handle in the next
release...  Anybody want to take a stab at it? ;-)
