 /dir1/dir2/file

  file and dir2 are deleted
  dir2 is re-added 
  file is re-added and dir2 version is now the 
       same as it was before it was deleted.

Same problem as before but one level higher.  You
would need to version all the way to the root, "/",
for this to work, wouldn't you?

Directory moves could create a similar problem:

  /dir1/dir2/file
  /dir1/dir3/file

  /file and dir2 deleted.
  dir3 moved to dir2 and happened to match file 
    and dir2 version #s.

but I think that versioning to the root would again
solve this?
