Shell prompt crazy for Git Submodules

I've run a somewhat odd little script to generate my command prompt for years now, sets some colors, adds some indicators of what kind of shell I'm in (sudo or tmux/screen or ssh or.. ).

Given I now have to work with git and submodules, I've revised that to include information provided about git generated by this script:

The difference is worth it, in understanding at a glance what is going on without typing git status or variant every two seconds. ;)

I've also been using some very useful aliases to make working with submodules sane, as documented here: Game On! Advanced Adventures / Git Submodules
