This version only addresses some issues with the tests, the actual logic remains untouched: - The test added in t7700-repack.sh that verifies that `--local` causes us to disable generation of the bitmap index was failing in the linux-TEST-vars CI job. This was because it sets GIT_TEST_MULTI_PACK_INDEX=3D1, which causes us to disable the bitmap logic in git-repack(1). I've fixed this failure by explicitly overriding the environment variable like other tests in the same file do. - I've converted path checks to use `test_path_is_missing` and `test_path_is_file` instead of `test ! -f` and `test -f`. - I've fixed a typo in t7703-repack-geometric.sh and shifted code around a bit to make the test more readable, following Derrick's suggestion. Thanks!
