[PATCH] NUL terminate diff-tree header lines under -z.
Thomas Glanzmann noticed that diff-tree -z HEAD piped to diff-helper -z did not work. Since diff-helper -z expects NUL terminated lines, we should generate such. The output side of the diff-helper should always be using '\n' termination; earlier it used the same line_termination used for the input side, which was a mistake.
