Very well. Yamamoto-san, I imagine this will mean you still have to maintain a
separate patch for Mac Port, but now covering only those features that the FSF
does not yet accept into GNU Emacs. All the rest of your work can be merged in
when you are ready. This should leave you with a much smaller patch to manage
separately.

I would like to see this work applied to the emacs-25 branch, as I have been
using it daily for years and can vouch for its readiness. We also need a new
section in the NEWS to describe what it offers as a build flavor for Mac
users, and a section in the INSTALL file describing how to select it.
