	Okay, I broke down and bought the three primary Python books -- 
Learning, Programming, and Nutshell.  Looking at the string 
functions, and not accounting for MIME encoding, Unicode encoding, or 
subject numbering, to my naïeve perspective, it looks like we should 
be able to turn this into something like the following:

      # Should we restore the original, non-prefixed subject for gatewayed
      # messages?
      origsubj = msgdata.get('origsubj')
      if not mlist.news_prefix_subject_too and origsubj is not None:
          stripped_subj = subject.replace(r'\s*'+subject_prefix+r'\s*', ' ')
          del msg['subject']
          msg['subject'] = stripped_subj


	The s.replace() function should grab any leading whitespace and 
trailing whitespace surrounding the subject_prefix, and replace all 
of that with a single space character.

	Now, to go off and look at CookHeaders.py and see just how far off I am....
