[Python-Dev] deprecated regex used by un-deprecated modules

Agreed.  There's an idiom to disable the warning, which you can find
in regsub.py:

    import warnings
    warnings.filterwarnings("ignore", "", DeprecationWarning, __name__)

(The "" should be replaced by the specific warning message though.)
