Can we do this by passing --ignore-submodules=none as the default args for status? Another approach might be to figure out how the diff is being called(like is this being called from git status or git diff) and then add the --ignore-submodules=untracked behavior to it accordingly. Though I have no idea how to do that now. Please correct me if I am completely going in the wrong direction. As it is my first time contributing to git, so any help would be greatly beneficial for me. Thanks and regards, Sangeeta
