Bug#184581: cdebconf/slang: Clears screen when skipping questions
When the debconf priority is higher then the question asked,
cdebconf/slang skips the question as it should. But before continuing
it will clear the screen and make it blue. I believe it should leave
the console untouched when skipping questions.
To see this behaviour, try booting with DEBCONF_PRIORITY=high, and
watch the screen clear every time the main menu should have asked
about how to continue.
This problem is also present in the newt frontend.
