[Rd] trace with reference class

Hi

The final line of the example in ?setRefClass induces an error:

> ## debugging all objects from class mEdit in method $undo()
> mEdit$trace(undo, browser)
Error in envRefInferField(x, what, getClass(class(x)), selfEnv) :
  'undo' is not a valid field or method name for reference class
"refGeneratorSlot"

$trace tries to embed the trace in the generator object (instead of
the generated object).
Has this functionality been removed?

best,

kohske
