In run_git_commit() we do
if (opts->gpg_sign)
strvec_pushf(&cmd.args, "-S%s", opts->gpg_sign);
else
strvec_push(&cmd.args, "--no-gpg-sign");
I'm not immediately clear why we pass --no-gpg-sign when opts->gpg_sign isn't set but it makes me wonder if we should be doing that here as well

This code path is used whenever the user specifies a merge strategy other than "recursive" or they pass merge strategy options to any merge strategy including "recursive" so while octopus merges may be rare the union of everything other than a plain recursive merge may not be.
