Test 2 of t5004-archive-corner-cases, "tar archive of empty tree is
empty", fails on Mac OS X 10.8.3 (with XCode 4.6.1) since the tar
command exits with return code 1 on the generated  tar file.

Hmm. So I guess the question is: do we need to work around this in the
test for platforms that do not like empty tar files, or are the empty
tarfiles we are making wrong somehow?

tar --version
bsdtar 2.8.3 - libarchive 2.8.3

It appears that bsdtar does not like the empty tar files created by
git archive. An empty tar file created by bsdtar is accepted.

tar cT /dev/null | tar t; echo $?
0

That makes me think the latter ("we are wrong"). I don't have my OS X
box handy; can you provide a sample empty tarfile that it creates?
