Thanks, that makes sense.

If I make the following change:
--- ../../bzr-0.92/bzrlib/mutabletree.py        2007-11-09
05:19:24.000000000 -0800

         for filepath in file_list:
-            rf = _FastPath(self.relpath(filepath))
+            rf = _FastPath(self.relpath(osutils.realpath(filepath)))
             # validate user parameters. Our recursive code avoids
adding new files
             # that need such validation
             if self.is_control_filename(rf.raw_path): 

then the test case I gave no longer fails.  (But I don't know if this is
a good general fix?)

Thanks,
Will
