For TAR archives, change file mode octal 0100666 to octal 000664

On Windows, (stat($file))[2] * ALWAYS * results in octal 0100666 (which means it is
world writeable). World writeable files are always rejected by PAUSE. The solution is to
change a file mode octal 0100666 to octal 000664, such that it is * NOT * world
writeable. This works on Windows, as well as on other systems (Linux, Mac, etc...), because
the filemode 0100666 only occurs on Windows. (If it occurred on Linux, it would be wrong anyway)
