bug#4368: 23.1; diff-hunk-kill -vs- final hunk in a file

[Tom Tromey]

Stefan> Can you show the content before the last M-k ?

The appended is a sample diff.  I just grabbed a couple random hunks
from the actual diff I was editing.  It was originally made by git.

Put it in a file, then M-x diff-mode.
M-n to go to the first @@.
M-k.

You will see that all the header info from lisp.h remains in the buffer.

I don't think you even need the second file diff in there to see this, a
single file will do.
