You never answered to this question. Neither on the list nor in your very rude 
private mail.

While it is true that this change does nothing bad, I still completely fail to 
see the point. I mean, hooray! you fixed one of a thousand ways to accidently 
delete "/". Unfortunately it's seldom the obvious way that this happens. 
Scripts might try to expand a variable that isn't there and do:
 rm -rf /${path}/
your "fix" won't help here. Or somebody types:
 rm -rf some_path /*
    extra whitespace due to unfortunate use of tab-completion

your "fix" doesn't help either. And so forth. So all the gain from this is 
added processing time, added code and an ego-boost for you (it seems to me).
