Instead of tracking the submodule at the specified branch, using a shallow
clone, we get the following error:

fatal: Cannot update paths and switch to branch 'anotherbranch' at the
same time.
Did you intend to checkout 'origin/anotherbranch' which can not be
resolved as commit?
Unable to checkout submodule 'submodule'

 Hi Carlos,

 I can reproduce your issue and have a patch which we can add to the
 testing suite to document this faulty behavior.

 Thanks,
 Stefan
