Patch for FilePlugin - bug 3649

[Tony Garnock-Jones]

Hi Ian.

I've found and fixed a problem in the Unix FilePlugin regarding
directory deletion. The problem is already covered by a test case in the
3.8 and 3.9 images. A description of the fault is here:
http://bugs.impara.de/view.php?id=3649 and I've attached the patch
against SVN trunk.

Regards,
  Tony
