Summary: Comparison of NaNs

Initial Comment:
In interactions pane, NaNs are compared incorrectly.
Example:
  double d = Double.NaN;
  d == d
  d == Double.NaN
both return true, which is incorrect. 
According to IEEE 754, all comparisons with a NaN must return false.
In non-interactive mode, the result of e.g. 
  System.out.println (d==d);
is correct, i.e. false.
