[PATCH v5 0/2] diff-files: integrate with sparse index

Changes since v4:

1. In 'diff-files with pathspec inside sparse definition' '

Add some extra space to make test more readable.

2.In 'diff-files with pathspec outside sparse definition' '

(1) Remove redundant tests since output from checkout and index are known to be identical.

(2) Add test to check sparse-checkout-err (sparse-index-err) is empty.

(3) Add test to test the actual output for 'file present on-disk with modifications'.
