         * InfoVarsCmd --
         *
         *	Called to implement the "info vars" command that returns the
         *	list of variables in the interpreter that match an optional pattern.
         *	The pattern, if any, consists of an optional sequence of namespace
         *	names separated by "::" qualifiers, which is followed by a
         *	glob-style pattern that restricts which variables are returned.
         *	Handles the following syntax:
         *
         *          info vars ?pattern?
         *
         * Results:
         *      Returns if successful, raises TclException otherwise.
         *
         * Side effects:
         *      Returns a result in the interpreter's result object.
         *
