Currently, if the s-o-b footer of a commit message contains a
"(cherry picked from ..." line that was added by a previous cherry-pick -x,
it is not recognized as a s-o-b footer and will cause a newline to be
inserted before an additional s-o-b is added.
So, rework ends_rfc2822_footer to recognize the "(cherry picked from ..."
string as part of the footer. Plus mark the test in t3511 as fixed.
