When running "format-patch" on a multiple patch series, the output coming from "--interdiff" and "--range-diff" options is inserted after the "shortlog" list of commits and the overall diffstat. The idea is that shortlog/diffstat are shorter and with denser information content, which gives a better overview before the readers dive into more details of range/inter diff. When working on a single patch, however, we stuff the inter/range diff output before the actual patch, next to the diffstat. This pushes down the patch text way down with inter/range diff output, distracting readers. Move the inter/range diff output to the very end of the output, after all the patch text is shown. As the inter/range diff is no longer part of the commentary block (i.e., what comes after the log message and "---", but before the patch text), stop producing "---" in the function that generates them.
