Update of /cvsroot/python/python/dist/src/Lib/test
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv2162/Lib/test

Modified Files:
	test_doctest.py 
Log Message:
Bugs fixed:

  - Test filenames sometimes had trailing .pyc or .pyo sufixes
    (when module __file__ did).

  - Trailing spaces spaces in expected output were dropped.

New default failure format:

  - Separation of examples from file info makes examples easier to see

  - More vertical separation, improving readability

  - Emacs-recognized file info (also closer to Python exception format)
