Change the pack-objects tests to not leave their .git directory corrupt and the end. In2fca19fbb5("fix multiple issues with t5300", 2010-02-03) a comment was added warning against adding any subsequent tests, but since4614043c8f("index-pack: use streaming interface for collision test on large blobs", 2012-05-24) the comment has drifted away from the code, mentioning two test, when we actually have three. Instead of having this warning let's just create a new .git directory specifically for these tests. As an aside, it would be interesting to instrument the test suite to run a "git fsck" at the very end (in "test_done"). That would have errored before this change, and may find other issues #leftoverbits. Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
