fatal error when merging a rename

The talk of merge corner cases made me remember this issue:

http://thread.gmane.org/gmane.comp.version-control.git/100859/focus=100956

The merge in the script below fails with this message:

fatal: git write-tree failed to write a tree

which is fixed by the (unapplied) patch from Alex in the thread above, but the worktree is still not updated even with that patch.

Cheers, Anders.
