Update of /cvsroot/python/python/nondist/sandbox/string/tests
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv27618/tests
Added Files:
	__init__.py test_pep292.py test_safedict.py 
Log Message:
Updated code and tests for PEP 292 proposal. I still need to write some
documentation, and it's not clear we're agreed on the approach of making the
string module a backward compatible package. But at least there's now a
strawman and some unit tests.
