OK. I change my scripts to use ".active" and it seems to work nicely.

I noticed one oddity, though:

If I clone a repo using `git clone --recursive <url>` then the local
Git config of the repo gets the following entry:

[submodule]
	active = .

Is this intentional? Something in the git/git test harness seems to prevent
that. I was not able to write a test to replicate the issue.

Any idea?

Thanks,
Lars
