Stephan Bergmann 29bc12777c Let loplugin:nullptr look into template instantiations 
It missed some occurrences of 0 when only looking into uninstantiated template
code, as Clang doesn't model them with an ImplicitCastExpr, even if the target
is known to be a (dependent) pointer type.

Looking into all template instantiations of course carries the risk that a given
use of 0 is meant to be interpreted as a pointer in some and as an integer in
other instantiations.  But the only case where that happened in the current code
base is RegistryValueList::getElement (include/registry/registry.hxx), where {}
is arguably a better choice anyway.  (And which would presumably also hold for
any future such cases.)
