We don't (yet) work with pull requests.  Please make the change in
your local clone of the Emacs repository, on the master branch, and
then use "git format-patch" to prepare a patch and post the patch
here.

(Please consult CONTRIBUTE in the repository for some of the practices
we advise to use with contributed code.)
