Hmm, this last line should probably be:
diff --git a/t/t1060-object-corruption.sh b/t/t1060-object-corruption.sh
index a84deb1..3f87051 100755

test_expect_success 'setup corrupt repo' '
The intent was to change a single byte, not truncate the file (though on
the plus side, that truncation is what found the other bugs).
