By the way, regarding what the right "--signoff" behavior is for
commit, cherry-pick, am, and format-patch:

I think the best behavior would be to check if the last signed-off-by
line (ignoring acked-by, bug, change-id, and so on lines that follow
it) matches the one to be added, and if it doesn't, add a new
sign-off.

This makes a lot of sense.
