When running xscreensaver without .xscreensaver or when running
xscreensaver-demo, the setup dialog appears. The dialog shows list of hacks, but
the list is ended with "providence" hack, not the last one (e.g. "zoom").
Steps to Reproduce:
1. apt-get install xscreensaver-frontend
2. rm .xscreensaver
3. xscreensaver-demo
4. exit xscreensaver-demo
5. grep "\\\n" .xscreensaver | tail -1
Actual Results:  
- GL:                           providence -root                            \n\

Expected Results:  
                                zoom -root                                   \n\

or something alike
