I'm processing some old patches I have lying around.  These clean up
git-subtree's test base and refactor the test code so that each test
is independent of the others.  This greatly aids debugging and
post-mortem analysis.

I have rebased these old patches on master, ensuring that new tests
that have been added in the interim are incorporated into the new test
code.

After using git-subtree in real projects for a couple of years and
exploring similar tools that have been developed, I'm fairly convinced
we should change some current behavor of git-subtree.  I have also run
into the need for some additional features.  I'm now in a position
where I can work on those.

This patch set is a prerequisite for that work.
