Before feeding minus and plus lines into xdi_diff, we replace non word
characters with '\n'. So we need recover the replaced character (always
the last character) in the callback fn_out_diff_words_aux.
Therefore, a common diff line beginning with ' ' is not always a real
common line. And we should check the last characters of the common diff
line. If they are different, we should output the first len-1 characters
as the common part and then the last characters in minus and plus
separately.
