combine-diff: special case --unified=0

Even when --unified=0 is given, the main loop to show the
combined textual diff needs to handle a line that is unchanged
but has lines that were deleted relative to a parent before it
(because that is where the lost lines hang).  However, such a
line should not be emitted in the final output.
