Reverted in r81964, marking as 3.2 only.

For 3.2, I'll get rid of the hack by having SetArgV treat both "-c" and "-m" as special values for sys.argv[0], and by adding some unit tests that make sure the presence of files with those names has no effect on the value of sys.path[0] when the corresponding command line switches are used.
