The wiki spec for this says that bzr will determine whether to use
case-insensitivity logic at runtime, not based on the platform or
filesystem type, but on whether opening a file (eg checkout/FORMAT)
under different case is possible or not.  So in this situation, it
presumably would observe the filesystem as being case-sensitive, and
will be able to handle both files sanely.

If the same filesystem is accessed sometimes in a case sensitive way
and sometimes not (whether on NT with SFU or maybe on a Samba share)
then we can't do the impossible, but we can have every bzr process
behave consistently within itself.
