don't collect dynamic variable names from cumulative reader

Browse Source 
we actually use variable values only from the exact reader, based on the
idea that the cumulative parse is too dangerous, as using recursive
watches on inexact data may be a bit heavy. using additional variable
names from the cumulative reader sort of defeats the idea.
