Comment #3 on issue 1034 by pekka.klarck: Do not process PYTHONPATH when
using Jython or IronPython

Now PYTHONPATH is processed again with Jython and IronPython.
Although I would like having ROBOTPATH that is supported with all
interpreters instead of processing PYTHONPATH, I don't think that's
worth the effort in near future.
