[Python-checkins] CVS: python/dist/src/Python compile.c,2.220,2.221

[Fred L. Drake]

Update of /cvsroot/python/python/dist/src/Python
In directory usw-pr-cvs1:/tmp/cvs-serv7596

Modified Files:
	compile.c 
Log Message:
When re-writing a factor containing a unary negation of a literal, only
affect nodes without another operator.  This was causing negated
exponentiations to drop the exponentiation.  This closes SF bug #456756.
