[Python-Dev] Adding a new C API function in 2.6

Hello, I would like to check that it's possible to a new C API function in the 2.6 branch, on the basis that it would help solve what seems to be reported as a security problem by several vendors (including Linux distributions) -- see http://bugs.python.org/issue5753 for a thorough discussion. The change is rather minimal at the code level; it adds a new function PySys_SetArgvEx which has an additional flag telling it whether to update sys.path or not. The existing PySys_SetArgv function unconditionally updates sys.path, which can allow shadowing of stdlib or third-party library modules by an attacker. Thank you Antoine.
