[AD] genexamp.py minor problem

[Evert Glebbeek <eglebbk@xxxxxxxxxx>]

The expackf example has a two line credit list. The genexamp.py script 
doesn't handle this properly at the moment: it assumes the second line is 
part of the example description. The fix would be to skip until the first 
blank line after the opening credits.
I worked around this for now by simply not applying the offending patch 
because my Python skills are too weak (as in, non existant) to do anything 
about it.
