diff is a more porcelain'ish command, while diff-index is closer to
the plumbing.  Therefore, diff contains some extra argument parsing/
pretty printing code that your script doesn't utilize -- use
diff-index.  Also, look at the various scripts in git.git to see what
they use; for example, require_clean_work_tree in git-sh-setup.sh.
