top: warn users if rcfile save prevents older top read

Browse Source 
I'm about to break older top rcfile compatibility when
preserving those two new toggles. And, though this has
happened several times over the years, we never issued
any warnings that such thing was just about to happen.

So, this patch corrects the long standing shortcoming.
