(I haven't checked the 'git am -s' behavior, but ...)

One distinction between commit, cherry-pick, am, and format-patch is
that the first three are related to importing commits _into_ your own
repository while format-patch is related to exporting patches _from_
your repository.

Not sure if an "exporting" operation should be treated differently from
an "importing" operation and mean "add my sign-off only if I did not
previously do so when I did commit, cherry-pick, or am" or whether it
should mean the same thing i.e. "append my sign-off, unless it's already

Just pointing something out that may or may not be useful.

Hmm, actually, this series could provide a data point.  When I submitted
the first series, I used 'format-patch -s' to append my sob.  When
Jonathan reviewed the series, he provided Acked-by and Reviewed-by which
I collected and added as I reworked the series.  When I added Jonathan's
Ack's/Rev-by's, I _appended_ them to the commits that I had already
submitted, so they appeared _after_ my own sob.  When I submitted the
later iterations of the series, I probably used 'format-patch -s' again
and I of course did not want an additional sob to be appended after
Jonathan's Acks.
