Hi Sangeeta,

First, thanks for correcting the test code that I've noticed in the previous mail (and thanks to Junio, who explained my words in better terms).

This rounds looks better to me. My only question now is: Should this change applicable to diff-index, diff-files and other plumbing commands?

As of it's now, we treat the absent of diff.ignoreSubmodules as "none" but we're changing to "untracked" with this change.

Will someone's scripts break by this change? I think it's unlikely, but who knows?

To contribute to the chaos, --ignore-submodules implies --ignore-submodules=all My first-quick-and-INCORRECT scan to the diff-options, I was puzzled by its default, and I thought (incorrectly, for a second) the absent of --ignore-submodules mean --ignore-submodules=all.
