I ran M-| bc on this region:

define fact(n) {
   if (n <= 1) return (n);
      return (n * fact(n-1));
}
fact(666)

The resulting very big number fills about 24 lines each terminated with
C-j. I then ran the following function

(defun unfill-paragraph () ;; bound to C-x M-q
  "Do the opposite of fill-paragraph; stuff all lines in the current
paragraph into a single long line."
  (interactive)
  (let ((fill-column 90002000))
    (fill-paragraph nil)))

on those 24 lines. Instead of joining them seamlessly, it puts in a space
where the C-j had been. I haven't noticed this happening with ordinary
text before. This happens with 21.3 on dos shell msw98.

???

Thanks,

Ed
