Fix potential invalid stack variable access in test code

Browse Source 
This code was (and is still) commented out but it *would* trigger
a "stack buffer overflow" error *if* uncommented.

The new code demonstrates how a binary object (Fl_Preferences 'bed')
can be dumped to a preferences file in binary format (if activated).
