[Python-checkins] python/dist/src/Objects stringobject.c, 2.223, 2.224

[arigo at users.sourceforge.net]

Update of /cvsroot/python/python/dist/src/Objects
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv21715/Objects

Modified Files:
	stringobject.c 
Log Message:
This was quite a dark bug in my recent in-place string concatenation
hack: it would resize *interned* strings in-place!  This occurred because
their reference counts do not have their expected value -- stringobject.c
hacks them.  Mea culpa.
