Re: [PATCH 6/6] format-patch --notes: show notes after three-dashes

> When inserting the note after the commit log message to format-patch
> output, add three dashes before the note.  Record the fact that we
> did so in the rev_info and omit showing duplicated three dashes in
> the usual codepath that is used when notes are not being shown.
