Before integrating the 'git diff-files' builtin with the sparse index feature, add tests to t1092-sparse-checkout-compatibility.sh to ensure it currently works with sparse-checkout and will still work with sparse index after that integration. When adding tests against a sparse-checkout definition, we test two modes: all changes are within the sparse-checkout cone and some changes are outside the sparse-checkout cone. In order to have staged changes outside of the sparse-checkout cone, create a 'newdirectory/testfile' and add it to the index, while leaving it outside of the sparse-checkout definition.Test 'newdirectory/testfile' being present on-disk without modifications, then change content inside 'newdirectory/testfile' in order to test 'newdirectory/testfile' being present on-disk with modifications.
