-v|--reroll-count=N
Try to extract the Nth version of a patch series, where these patches are identified by subject
prefixes like "[PATCH vN 1/3]".
If this option is not specified, and there is more than one series, default to extracting the version
of the patch series with the highest version number we find.
Note that this option should not usually be needed, because best practices when sharing patches with
git-send-email(1) include starting a new thread when posting a revised series. The --in-reply-to
option to git-format-patch(1) is used mainly for posting a patch series in reply to a bug report.
--trailers
Extract and add to patches lines like
Acked-by: A. Developer <a.dev@example.net>
sent in reply to those patches. --trailers is on by default, and --no-trailers can be used to
disable adding the trailers.
--cover-letter-trailers
Additionally add to all patches in the series any trailers sent in reply to the cover letter of the
patch series.
