[Ifeffit] Energy shift in exported data

Hello, I have noticed the following behavior in Athena 0.9.20 on OSX 10.8.5. If a group with an energy shift applied is exported as norm(E) using the export marked groups option then the energy shift is not preserved in the .nor file. If the export current group option is used then the energy shift is preserved. This seems to be general behavior and should be straightforward to reproduce, but I can provide an example project if needed. Thank you, George
