Right now, the test suite can be run with 'GIT_TEST_WRITE_REV_INDEX=1'
in the environment, which causes all operations which write a pack to
also write a .rev file.
To prepare for when that eventually becomes the default, we should
continue to test the in-memory reverse index, too, in order to avoid
losing existing coverage. Unfortunately, explicit existing coverage is
rather sparse, so only a basic test is added that compares the result of
git rev-list --objects --no-object-names --all |
git cat-file --batch-check='%(objectsize:disk) %(objectname)'
with and without an on-disk reverse index.
