# Detect the exit code produced when our particular flavor of unzip | |

# implementations to do the same thing (it would be perfectly | |
# reasonable to exit 0, for example). | |
# | |
# This makes our test less rigorous on some platforms (unzip may not | |
# handle the empty repo at all, making our later check of its exit code | |
# a no-op). But we cannot do anything reasonable except skip the test | |
# on such platforms anyway, and this is the moral equivalent. | |
