diffutils 2.8: newlines not ignored under -w

[Karl Berry]

In diffutils 2.8 (tried both solaris 2.7 and gnu/linux), diff -w does
not ignore newlines, although the manual (node White Space) says it
should:

$ cat f1
line1

$ cat f2
line1
$ diff -w f1 f2
2d1
< 


Shouldn't diff come back with nothing in this case?
