[PATCH 0/3] Update submodule documentation

I think I sent out the first 2 patches once upon a time, but the review
or me resending them stalled. They improve the man page for the git-submodule
command.

The third patch is RFC-ish and adds a background story to submodules
Similar to gitattributes, gitnamespaces, gittutorial it doesn't describe
a particular command but e.g. explains design.

Thanks,
Stefan
