[Python-Dev] tests expecting but not finding errors due to bug fixes

[Alex Martelli]

Switching to the 2.3 maintenance branch (where test_bsdddb runs just fine),
I got "make test" failures on test_re.py.  Turns out that the 2.3-branch 
test_re.py was apparently not updated when the RE recursion bug was
fixed -- it still expects a couple of exceptions to be raised and they don't
get raised any more because the bugfix itself WAS backported.

On general principles, in cases of this ilk, IS it all right to just backport 
the corrected unit-test (from the 2.4 to the 2.3 branch) and commit the
fix, or should one be more circumspect about it...?
