[PATCH] cherry-pick -x: always insert an empty line

[PATCH] cherry-pick -x: always insert an empty line

[Beat Bolli]

When cherry-picking a commit that has only a summary, the -x option
creates an invalid commit message because it puts the hash of the commit
being picked on the second line which should be left empty.

This patch fixes this buglet by always inserting an empty line before
the added line.

Aside from that, even with a non-trivial commit the generated note
"(cherry picked from commit 555c9864971744abb558796aea28e12a1ac20839)"
seems abrupt when appended directly.

Doesn't this need to be conditional?

If we cherry pick your commit somewhere else with "-x -s", the resulting
commit log message would end like this:

    Aside from that, even with a non-trivial commit the generated note
    "(cherry picked from commit 555c9864971744abb558796aea28e12a1ac20839)"
    seems abrupt when appended directly.

    Cc: Eric Raible <raible@nextest.com>
    Signed-off-by: Beat Bolli <bbolli@ewanet.ch>

    (cherry picked from commit 555c9864971744abb558796aea28e12a1ac20839)
    Signed-off-by: Frotz Xyzzy <nitfol@example.xz>

which clearly is worse-looking with the extra LF you added in this patch.

What should the condition then be? What is the canonical format for
cherry-picks with Signed-off-by: and Cc: footer lines?

Clearly? I would not say so, on the contrary. When using -s together 
with -x, I'd interpret this as signing off the process of cherry-picking 
itself, and as such, visually grouping the additional "signed-off" with 
the "cherry picked from" makes sense to me.

Thanks for this! Not having an empty line there has annoyed me, too, 
several times.
