[Python-checkins] CVS: python/dist/src/Lib/test test_long.py,1.3,1.4

[Guido van Rossum]

Update of /projects/cvsroot/python/dist/src/Lib/test
In directory eric:/projects/python/develop/guido/src/Lib/test

Modified Files:
	test_long.py 
Log Message:
Christian Tismer: added test to ensure that multiplication commutes.

[The test is in a slightly odd place, in test_division_2; but it
exercises the recent change to long_mult(), and that's all we really
ask for.  --GvR]
