When 'cherry-pick -s' is used to append a signed-off-by line to a cherry
picked commit, it does not currently detect the "(cherry picked from..."
that may have been appended by a previous 'cherry-pick -x' as part of the
s-o-b footer and it will insert a blank line before appending a new s-o-b.
Let's detect "(cherry picked from...)" as part of the footer so that we
will produce this:
Signed-off-by: A U Thor <author@xxxxxxxxxxx>
(cherry picked from da39a3ee5e6b4b0d3255bfef95601890afd80709)
Signed-off-by: C O Mmitter <committer@xxxxxxxxxxx>
instead of this:
Signed-off-by: A U Thor <author@xxxxxxxxxxx>
(cherry picked from da39a3ee5e6b4b0d3255bfef95601890afd80709)
Signed-off-by: C O Mmitter <committer@xxxxxxxxxxx>
