Normalize Zero Vector?

[DiamondToaster]

So, I've noticed that for a while, normalizing a zero-distance vector returns a nil value. Should this be fixed to return a zero vector? According to people on Stack Overflow, the normalized form of a zero vector is also a zero vector This would be useful so I don't have to check for nil values and use hackish workarounds.
