If the documentation doesn't support word splitting in that case,
then it's the documentation that will need to change, not the shell.

Word splitting in that context is *frequently* used in scripts.  Never
mind the fact that it's dangerous and wrong -- people use it, a lot.
A change to the shell that would stop it from occurring would break
countless scripts.
