   deck-log -- the boat's records.

   Two modes, as everywhere in this suite, and they are not light-and-
   dark. Dark is normal. NIGHT is red-on-black because the three-hourly
   entry falls at 0300 as often as at 1500, and dark adaptation takes
   twenty minutes to build and a second to lose.

   One rule governs the entry screens: a state carried forward is shown
   as a default, a measurement never is. The two look different on
   purpose -- a field with a default shows it in the box, a field
   without shows nothing at all -- because the whole point is that
   return means "yes, still" in one case and "not taken" in the other.
