I'll tentatively queue this on jl/git-gui-show-added-submodule-changes
and park it on 'pu'.

I'll be tagging 2.0.0-rc0 later this week; if you have some
accumulated changes (I saw that your public repository is at
gitgui-0.19.0 which I already have), please plan to get them
in by the end of next week.

Thanks.
