This test has never leaked since it was added. Let's annotate it to make sure it stays that way (and to reduce noise when looking for other leak-free scripts after we fix some leaks). Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

# default is enough to prevent segfaults on systems that run the tests.

# 1. It's faster than creating $big_depth tree objects.

|

# 2. As we tighten tree limits, it's more likely to allow large sizes
|
|
# than trying to stuff a deep path into the index.
