Very pleasing to see this.

I would imagine that an equally easy to understand and more compact
presentation of this series would have been to

 - copy minimally needed code to git-submodule.sh verbatim, while
   dropping the dot-source from git-submodule.sh (patch 1)

 - just say "nobody now dot-sources this shell library" and do what
   this step does.

Especially 1/5 confused me more than it helped me to understand the
end result ;-)  It does not matter in the endgame that GIT_DIR was
defined there, as long as we know nobody other than git-submodule.sh
dot-sources the shell library and git-submodule.sh uses its own setup.

But that can only be said with perfect hindsight after seeing all
your efforts in these five patches.

Thanks.
