abandon attempts to make wxAnyStrPtr behave as bool: user-defined logical operators don't short circuit silently breaking existing code so it is better to not provide them at all; instead simply return bool from the new versions taking wxString::const_iterator; advise to use the new versions in the new code and so in our own files
