tests: reduce spurious failures when run with generaldelta Quite a few tests fail in noisy but meaningless ways when the test suite is run with generaldelta enabled: ./run-tests.py --extra-config-opt=format.generaldelta=1 This reduces the amount of noise introduced by the debugindex command, the main source of differences. In my environment, when testing with generaldelta enabled, this change reduces the number of completely failing tests from 21 to 8.
