Edit: my comment below was uninformed, I see that Mituharu's port is up-do-date with Emacs 25, which is close enough to upstream for me. Original: Interesting

Edit: my comment below was uninformed, I see that Mituharu's port is up-do-date with Emacs 25, which is close enough to upstream for me. Original: Interesting! However, how closely does it follow upstream for... every other feature? I'm using GNU Emacs because I've basically standardized my use of it across platforms. Gone are the days of XEmacs vs Emacs and all the small differences between them, and GNU Emacs' development pace has nicely picked up over the past 2-3 years since Stallman stepped down as maintainer.
