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

[Beat Bolli <bbolli@ewanet.ch>]

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.
