See what Junio says, I think it might be simple enough for him to fix
that up when he merges it into pu.
I've just realized that if you're cherry-picking a range of commits and
it stops for a conflict resolution then the new option is not saved.
You'll need to update populate_opts_cb() and save_opts() in sequencer.c
to do that.
