SF patch #413552 - Premature decref on object Jeffery Collins pointed out that filterstring decrefs a character object before it's done using it. This works by accident today because another module always happens to have an active reference too at the time. The accident doesn't work after his Pippy modifications, and since it *is* an accident even in the mainline Python, it should work by design there too. The patch accomplishes that.
