Yep, you're correct.  I misunderstood that output.

I'm now at the point where the README
(https://git.savannah.gnu.org/cgit/emacs/nongnu.git/tree/README.org#n241)
tells me to git push which is failing because I don't have
permissions.  I don't think I have such permissions so that makes
sense.  I asked in the emacs IRC channel and the suggestion was to
mail the patch to the emacs-devel mailing list.  Is this the correct
way to submit code?  I don't mind mailing a patch but it's a process
I've never worked with before.

I've noted https://www.gnu.org/software/emacs/manual/html_node/emacs/Sending-Patches.html
as well, which suggests sending patches to the bug-gnu-emacs mailing
list.  That list appears to only be applicable to existing bugs
though, which I don't currently have.

Any suggestions for how to continue?  I've tried to attach my patch
here for reference.
