        Also, detect syntax errors before security errors; some syntax errors
        will also trigger a security error, but it's more helpful to the
        programmer to know if they have a syntax error, which are well-defined
        in the spec, rather than a security error, which aren't.

        * page/Navigator.cpp:
        (WebCore::Navigator::registerProtocolHandler):
        Detect syntax errors before security errors.
        * platform/KURLGoogle.cpp:
        (WebCore::isSchemeChar):
        Include '+' in the list of valid characters.
