I've fixed the glitches, now both versions (argparse and optparse) are 
supported. Still, optparse's code performs a bit faster and doesn't need a 
couple of HACKs that are necessary for optparse's code to run. If all tests 
perform correctly, I'll merge the branch into master.

So, no upgrade problems, nor optparse embedding issues :)

I did want to rewrite the module beacuse I think that clarity of 
implementation should win over milliseconds of speed. Which, I think, is the 
very same spirit on which Python is founded.
