Nit: for this kind of case of forwarding someone else's patch, we put
a From field at the beginning of the body of the message. "git
format-patch" can produce a message with that format if you commit
with 'git commit --author="Someone Else <person@example.com>"' and run
format-patch with --from="My Name <me@example.com>". More details are
in the DISCUSSION section of git-format-patch(1).
As with v3, since v2 is already in "next" this should go incremental.

Are there example callers that this version fixes? Where can I read
more, or what can I run to experience it?
For example, v2.19.0-rc0~45^2~2 (http-backend: respect CONTENT_LENGTH
as specified by rfc3875, 2018-06-10) mentions IIS/Windows; does IIS
make use of this distinction?
Thanks,
Jonathan
