   1 maintenance.<task>.enabled::
   2         This boolean config option controls whether the maintenance task
   3         with name `<task>` is run when no `--task` option is specified to
   4         `git maintenance run`. These config values are ignored if a
   5         `--task` option exists. By default, only `maintenance.gc.enabled`
   6         is true.
   7
   8 maintenance.commit-graph.auto::
   9         This integer config option controls how often the `commit-graph` task
  10         should be run as part of `git maintenance run --auto`. If zero, then
  11         the `commit-graph` task will not run with the `--auto` option. A
  12         negative value will force the task to run every time. Otherwise, a
  13         positive value implies the command should run when the number of
  14         reachable commits that are not in the commit-graph file is at least
  15         the value of `maintenance.commit-graph.auto`. The default value is
  16         100.
