CC Mode 5.28 (C++); C++ uppercase manipulator misinterpreted as switch label

CC Mode 5.28 (C++); C++ uppercase manipulator misinterpreted as switch label

[Tim Bagot]

This C++ snippet receives incorrect indentation:

void Foo()
{
    os << std::uppercase << std::hex;
                        // This line gets statement-case-intro
}

The problem appears to be here (in cc-langs.el):

;; Regexp describing a switch's case or default label for all languages
(defconst c-switch-label-key "\\(\\(case[( \t]+\\S .*\\)\\|default[ \t]*\\):")

It sees a case label where there is none. I think something like a \< at
the start of the regexp should fix it.
