Adding new tests for new status command

This is a work in progress.  This adds two new sets of tests,
the issue_592 tests from @nulltoken's pull request #601 and
some new tests for submodules.  The submodule tests still have
issues where the status is not reported correctly.  That needs
to be fixed before merge.
