I had originally deleted this last test, so they would pass (it was not only 
on Windows), so a simple "svn up" should have sufficed. However, I just 
reenabled the test and fixed it for good.

Right, I know about this. Mmh, in fact, it surprises me now that my 
deprecation module doctests do not complain in the second run. It is probably 
one of the advantages of doc file tests, since their module gets regenerated 
for every test run, so that the deprecation framework does not detect the 
warning duplication.
