Since I had no interesting books to read today, nor interesting films to watch, I decided to scavenge for the most intriguing content one can find online. I ended up reading the Linux kernel mailing lists, but those discussions seemed to be 18+, so I settled for the comparatively civil emacs-devel. For those unfamiliar, emacs-devel is the primary development discussion list for GNU Emacs – where design decisions get made, patches get reviewed, and occasionally where people spend 200 messages arguing about version control software. This is the story of that last one.
