			Python now gets the absolute path of the script filename specified on the command line (ex: "python3 script.py"): the __file__ attribute of the __main__ module, sys.argv[0] and sys.path[0] become an absolute path, rather than a relative path. * Add _Py_isabs() and _Py_abspath() functions. * _PyConfig_Read() now tries to get the absolute path of run_filename, but keeps the relative path if _Py_abspath() fails. * Reimplement os._getfullpathname() using _Py_abspath(). * Use _Py_isabs() in getpath.c.
