[Python-Dev] test_quopri is iso-latin-1 centric

Well, exactly because Python source code is not in Latin-1, the
test_quopri.py file is wrong IMO, because it uses non-ASCII
characters.  So please go ahead and change it into hex constants...

(This doesn't occur on Windows because, I'm assuming, the Windows CVS
client isn't as "smart" as the Mac CVS client.)
