This application was started with Python 1.4.  We still use Python 2.2,
which has some subtle but critical differences with the way new-style
classes are handled in 2.3+.  Using super() makes our plugin model work;
otherwise, we'd have to switch to a non-cooperative mechanism for calling
plugin hooks.  That would have some advantages, of course, but so much
code would need rewriting, and managing the calling of plugin hooks would
require creating an API registry.

The world is not always a simple place....

"...string iteration isn't about treating strings as sequences of strings, 
it's about treating strings as sequences of characters.  The fact that
characters are also strings is the reason we have problems, but characters 
are strings for other good reasons."  --Aahz
