+** diff mode
+Oh diffs; the way of the ancient ones.  Nowadays we use our newfangled
+"pull requests" and "cool web interfaces" to handle change management
+in our code repositories, but the old school projects use patches to
+make code changes.  I actually somewhat like patches, if only for
+their simplicity in concept.

+new features and Emacs has great functionality to work with patches
+effectively.  Here I configure ~diff-mode~, which provides most of this
+cool stuff, to be a bit more ergonomic with ~evil~.
