. ./test-lib.sh

# This test covers a weird 3-way interaction between "--cc -p", which will run
# the combined diff code, along with "--stat", which will be computed as a
# first-parent stat during the combined diff, and "--color-moved", which
# enables the emitted_symbols list to store the diff in memory.
