Re: [PATCH v2 1/2] sequencer: fix gpg option passed to merge subcommand

> 
> When performing a rebase with --rebase-merges using either a custom
> strategy specified with -s or an octopus merge, and at the same time
> having gpgsign enabled (either rebase -S or config commit.gpgsign), the
> operation would fail on making the merge commit. Instead of "-S%s" with
> the key id substituted, only the bare key id would get passed to the
> underlying merge command, which tried to interpret it as a ref.
