[PATCH v2 0/1] doc: Document 'git submodule status --cached'

It's currently undocumented, and should be mentioned.

I previously thought that git submodule status was displaying the behaviors of git submodule status --cached and was thus incorrectly documented, but that wasn't actually the case: turns out that git submodule status just doesn't work when not in the root directory.
