Description of problem:
If you type Alt-N one too many times, you'll skip the package selection screen
and there won't be any way to go back and change the selection, the installer
will proceed to the install without the final no-going-back-past-this-point
screen that appears on a non-kickstart install.

Version-Release number of selected component (if applicable):
anaconda-10.92.4-1

How reproducible:
Every time

Steps to Reproduce:
1.Start an interactive kickstart install
2.On the package selection screen, click on Next
  
Actual results:
It starts installing immediately

Expected results:
It should give the user the option to go back and fix things up, or type a
keystroke other than Alt-N to start the install
