diff-files is scriptable plumbing, which means it is up to the script
writer to decide exactly when the index should be refreshed with respect
to the working tree files (because doing so could be kind of expensive,
as it needs to stat every file in the working tree). Have you tried
running "git update-index --refresh" just before your diff-files?
