Agreed, this seems to be the most elegant solution. It seems to be a 
step in the right direction and removes the regression with the test 
setup described on the wiki and used by the buildbot. Pushed to crew, 
thanks.

This cleanup means that we should avoid using $TESTTMP and $TESTDIR in 
places where sh can see them ... but that is fortunately not much of a 
problem.

We still have the 'xC:/x' problem in the places where we use `pwd` ... 
because of the alias. That could perhaps be avoided somehow, but for now 
I have pushed some workarounds.
