* 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.
