Constant Vector as Argument in PPL

[ftneek]

Mentioning the behavior of the Prime across hardware versions/firmware revisions can help the developers pinpoint when a bug is introduced, making it easier to track down and fix.

Indeed, on a physical calculator the program behaves as you describe while normalize([0,0,-1]) correctly returns [0,0,-1] in Home view. I will file a ticket on the bug tracker, let's hope it can be resolved.
