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

[Walter Dörwald]

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?
