Comment (by oerjan):

 Well I ''could'' continue to quibble about the current design's intrinsic
 lack of support for my strange test cases in the discussion of comments
 [comment:43] - [comment:47] and the IMO more reasonable one in comment
 [comment:79]. Of course I was trying to imagine maximal backwards
 compatibility there.

 However, I realize the current design is much less complicated, and
 apparently works for what people actually do.

 I don't see any further actual exploits at this time. :)
