1) If top-level is on a detached head, then the remotes machinery will 
find current remote is "origin". This is what would be passed down the 
chain.

2) Absent the other changes in the thread, git-submodule-init still 
invokes   git clone *without* -o in the submodules, and thus still 
defines and points to remote "origin".
