I've merged in the test change and resent, but haven't run the tests
on Windows. The Windows testing patch queue doesn't apply cleanly to
current crew tip, and I'm afraid I don't have time to rebase it
tonight.

Paul.

PS Are the Windows testing patches ever likely to be merged into
Mercurial, so there's no need for this rigmarole of rebasing and
applying the patch series? It's not hard, but I often find it takes
more (manual) effort than I have time for, as compared to simply
firing off a test run.
