  1) Fix longstanding math bug with denominator > 1 (wrong probability).
  Test case:
          random -f some_small_file 10000
  (in most cases must be no output)
  2) Prevent number of lines > RANDOM_MAX (overflow or nothing may be
  choosed) with EFBIG err()
  3) After line is found, terminate list loop for -U case too,
  since nothing to do in the rest of the loop left.
