Add a newline before appending "Signed-off-by: " line

Browse source 
Whef the last line of the commit log message does not end with
"^[-A-Za-z]+: [^@]+@", append a newline after it to separate
the body of the commit log message from the run of sign-off and
ack lines. e.g. "Signed-off-by: A U Thor <au.thor@example.com>" or
"Acked-by: Me <myself@example.org>".
