Bleah. Whether or not the nearest copy of tar happens to spit up on
that, it's a clear violation of the POSIX standard for tar files.
I'd vote for back-patching your 0001.
I'd lean mildly to holding 0002 until after we branch. It probably
won't break anything, but it probably won't fix anything either.
