Looks good to me except for the line count on the @@ line.  The
preimage ought to have 6 (not 7) lines and adding 4 new lines makes
it a 10 line postimage.  I wonder who miscounted the hunk---it is
immediately followed by the signature cut mark "-- \n" and some
tools (including Emacs's patch editing mode) are known to
misinterpret it as a preimage line that was removed.

What is curious is that your 2/2 counts the preimage lines
correctly.

In any case, both patches look good.  Will apply.

Thanks.
