Ah, then we have a docbug.
git help config has this to say:

url.<base>.insteadOf
     Any URL that starts with this value will be rewritten to start,
     instead, with <base>.

The "Any" here is wrong, it would be "any except submodule" (possibly 
other exceptions).

Exactly.
My thinking was that since the submodule URLs are specified in the super 
project's .gitmodules, that setting should apply.

It would certainly help me out, though I guess it's going to be too late 
for my current project :-)

No can do - that's under version control.
My personal setup does not belong there I think ;-)

I am currently trying to write a shell script that
- does git submodule init
- pulls submodule configuration out of git config -l
- configures each submodule with insteadOf
It fits with my workflow because setting up the repositories is going to 
be done via script anyway.
I'm neither a shell nor a git expert, so any advice still appreciated.
