+;;; Commentary:
+
+;; This works, but since magit-log uses overlays for the committer and
+;; date on each line, those are lost when we erase the buffer. Fixing
+;; that would require copying the properties of those overlays into
+;; the text properties of each line. Probably not worth it, since
+;; this is just a demo, anyway.
