[Python-Dev] SF patch #677429 (PEP293 callbacks)

SF patch #677429 (Out of bounds indizes in PEP293 callbacks) fixes a small open issue with PEP293 callbacks: How to treat negative or out-of-bounds positions returned from an error callback. This was unspecified before (the implementation silently clipped values to the valid range). MvL discovered that and requested that to PEP and docs are clarified and the implementation fixed. MvL is on vacation, so can somebody else review the patch, so it gets in before 2.3a2? Bye, Walter Dörwald
