+## Default git commit message when none provided
+
+Ikiwiki and a recent enough version of git allow for empty git messages (the "Optional description of this change" while editing on the web), that's nice but it makes stagit history impossible to browse because it uses such messages as links. To make ikiwiki provide a default commit message when non given, you can do this:
