I think we had an exchange to clarify the workflow in which
updateInstead is useful and how to help readers, but I do not see
any change on that in this part of documentation.  Forgot to revise?

OK.

"update-index --refresh && diff-files && diff-index --cached" is how
we traditionally ensure the working tree is absolutely clean (see
require_clean_work_tree in git-sh-setup.sh), but I do not think of a
reason why diff-files step is not redundant.  As a totally separate
topic outside this series, we may want to visit that shell function.
