Is there a way that rsync will find different case files in destination and will
update the filename without copying the whole file? Kind of a special case of
the "find existing" patch. This is something that might be useful even on
case-sensitive filesystems as on linux. As only the case has changed
it may be a lot easier to implement than a full search for the file.
