add: skip tracked paths outside sparse-checkout cone
When 'git add' adds a tracked file that is outside of the sparse-checkout cone, it checks the SKIP_WORKTREE bit to see if the file exists outside of the sparse-checkout cone. This is usually correct, except in the case of a merge conflict outside of the cone. Modify add_pathspec_matched_against_index() to be more careful about paths by checking the sparse-checkout patterns in addition to the SKIP_WORKTREE bit. This causes 'git add' to no longer allow files outside of the cone that removed the SKIP_WORKTREE bit due to a merge conflict. With only this change, users will only be able to add the file after adding the file to the sparse-checkout cone. A later change will allow users to force adding even though the file is outside of the sparse-checkout cone.
