[Python-checkins] CVS: python/dist/src/Lib/test test_descr.py,1.44,1.45

[Tim Peters]

Update of /cvsroot/python/python/dist/src/Lib/test
In directory usw-pr-cvs1:/tmp/cvs-serv24631/python/Lib/test

Modified Files:
	test_descr.py 
Log Message:
More bug 460020:  lots of string optimizations inhibited for string
subclasses, all "the usual" ones (slicing etc), plus replace, translate,
ljust, rjust, center and strip.  I don't know how to be sure they've all
been caught.

Question:  Should we complain if someone tries to intern an instance of
a string subclass?  I hate to slow any code on those paths.
