Don't try to rewrite NEW references in a utility statement in a rule.

Browse Source 
There won't be any, and in fact there won't even be an RTE for NEW,
which was leading to a core dump in CVS tip.  7.4 and earlier manage
not to crash when applying ResolveNew in this scenario, but I think
it was just good fortune that they didn't.  Per report from
Bernd Helmle.
