ok, i've generated a single test_pep380.py using greg tests wrapped to be
run by unittest.
it's ugly, but it does the job.
some things that may not be desirable:
- line numbers in the tracebacks do rely on the position of the tests in the 
file, so any editing before the last test case will probably screw up 
- the test touches sys.stdout & sys.stderr

the whole thing is available here:


ps. i had to edit the test24 (Test parser module) expected output to make it
match the actual output, i guess that the parser module has changed since greg
wrote the tests.
