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, make a directory called 'folder1' and copy `a` into 'folder1/a'. 'folder1/a' is identical to `a` in the base commit. These make 'folder1/a' in the index, while leaving it outside of the sparse-checkout definition. Change content inside 'folder1/a' in order to test 'folder1/a' being present on-disk with modifications.
