Run this to see demonstration of the bug:

(with-temp-buffer
  (let ((str "One Line here and some text \
Second line here and some text \
Third line here and some text\n")
        (fill-column 20)
        (fill-prefix ">> "))
    (insert str)
    (display-buffer (current-buffer))
    (read-string "Text before [press] ")
    (goto-char (point-min))
    (fill-paragraph nil)
    (read-string "Text after fill [press] ")))

BEFORE:

One Line here and some text Second line here and some text Third line here and some text

AFTER:

One Line here and
>> some text Second
>> line here and
>> some text Third
>> line here and
>> some text

The first line should also have ">> "
