Ah, yes, I am not thinking very well.  Please forget what I said before.

v1.5.3-rc5~10 (git-diff: squelch "empty" diffs, 2007-08-03) has the
answer for your question.  I am not sure I agree with its conclusion.

v1.5.3~8 (git-diff: resurrect the traditional empty "diff --git"
behaviour, 2007-08-31) tweaked the porcelain more by dropping the
warning message and adding the diff.autorefreshindex variable.

What is missing is a --refresh-index option for diff-files and
diff-index, to make it easy for porcelain, especially long-running
porcelain like gitk.
