mystery bits in readnews
    While looking for some mysterious bugs, I tried making the get, set,
and test bit macros in readnews into routines that do the same thing but
check to see if the bit number is inside the bit array.  Amazingly
enough, frequently it is not.  Evidently this produces no problems, but
it's sheer luck that it doesn't.  Look at the place in readr() where bit
is set to -1 for an example of invalid bit numbers.
