Update of /cvsroot/python/python/dist/src/Lib/test
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv14073/Lib/test

Modified Files:
	test_doctest.py 
Log Message:
Reverted the addition of a NORMALIZE_NUMBERS option, per Tim Peter's
request.  Tim says that "correct 'fuzzy' comparison of floats cannot
be automated."  (The motivation behind adding the new option         
was verifying interactive examples in Python's latex documentation; 
several such examples use numbers that don't print consistently on
different platforms.)

 The ELLIPSIS flag causes ellipsis marker ("...") in the expected
 output to match any substring in the actual output:
