Well from the superprojects perspective a submodule looks like a file,
so if the checkout involved removing a file it had to either be clean or the
checkout failed. So I though we'd go with a similar way here?
We need to stop when untracked files are present, I am not sure if we need
to care if the files are ignored, though.
In this version of the series, the test added in patch 14, testing for
treating untracked files properly is a failing test. So I agree that we should
not just delete them; I'll fix that in the next version of the series.
Thanks,
Stefan
