dirstate-v2: Update the expected output of some tests for new requirement Fix most test failures (except in test-narrow-debugrebuilddirstate.t and test-upgrade-repo.t) caused by the new entry in config or in .hg/requires when running `run-tests.py --extra-config-opt format.exp-dirstate-v2=1` There is no CI?so far for this configuration.
