And here 'tis. I didn't commit because I have no way to test whether
I broke the Windows code path. Please test, and commit if OK.
There is an unfinished TODO item here: we really ought to make it work
for tar-format archives. That's probably not hugely difficult, but
I didn't look into it, and don't think we should hold up applying the
existing patch for it.
