  It's not really a question of advantages so much as minimizing losses;
since CVS has hackery that sometimes readds the missing newline, we need
to either (a) put awareness of that hackery into diffutils code (which is
very ugly, but simple and small), or (b) get rid of that hackery, which
presumably will complexify the CVS code somewhat (which is right, but
might be complex and big.)  Without one of those, we get incorrect
behavior.  I did (a) for various reasons; I'll take a crack at (b) this
weekend unless someone can suggest a third option.  Maybe we'll get
lucky and something like putting a newline right past the end of the
buffer will suffice.

  Yah, that makes sense.
