+maintenance.<task>.enabled::
+	This boolean config option controls whether the maintenance task
+	with name `<task>` is run when no `--task` option is specified to
+	`git maintenance run`. These config values are ignored if a
+	`--task` option exists. By default, only `maintenance.gc.enabled`
+	is true.
