Does 'zip' preserve timestamps? Later in the mail, Richard says:

    The only differences between the two wc:s, as far as we can see,
    is in the file timestamps.

So, it sounds like a byte-for-byte comparison shows no differences, unless
you include the bytes associated with inodes and their timestamps.
