# Note: this repo script does not produce a byte-for-byte copy of the original.
#
# The 'git init' operation in the nested Git repo creates some sample files
# whose contents depend on the exact Git version in use, and the steps we take
# to construct a fake 'git clone' status don't produce some log files that
# a real 'git clone' leaves behind.
#
# However, the repo is probably accurate enough for the tests that need it.
