If "if()" is never fixed people will still run into that and be
confused.  Adding another command will leave people with the
decision about which one to use in what cases and be even more
confused.

As I have explained every other time it has come up there is exactly
one way to fix it: a policy that makes expansion happen only for
unquoted arguments.  Someone just has to do it.
