Shouldn't this (and possibly the other one, I didn't look at the
patch text) be using the internal machinery used by interpret-trailers
so that we can do the usual "do not duplicated existing ones",
"append only at the last one is different" etc.?

I also do not think we want to see one option (like the above) for
each trailer elements (like "Reviewed-by") that is commonly used,
which would lead us to adding "--helped-by", "--acked-by", etc. to
complement this one.
