Subject: [PATCH] Fix Coverity issue reported for setslice (pycontainer.swg):

"CID 11151 (#3-1 of 3): Using invalid iterator (INVALIDATE_ITERATOR)18.
increment_iterator: Incrementing iterator it though it is already past
the end of its container."

Coverity does not understand 'replace_count', so warns that we may go
past self->end() (or self->rend() I guess).
