How is the cherry-pick event different from the send-by-mail-and-apply
event?

In both cases, the result has a distinct commit id and distinct
signoff and it is unlikely that the previous patch handler was testing
with the same tree as the next one.  (And each patch handler should add
relevant comments if the new situation warrants that.)
