Boring - Well, this problem has been known for quite some time now; I have absolutely no idea why it’s still being examined. As long as you’re checking the VMS at the token level, it can’t be a language. Everyone should know that—either the spaces aren’t spaces, or it isn’t a language. My conclusion: The spaces are not spaces. 
The starting and ending glyphs are closely related. Yes, exactly, and that’s the reason, why the spaces shouldn't seen as spaces, too. And as soon as you realize that, all these investigations vanish into thin air.
