**
**    off                    Never autosync.
**
**    pullonly               Only to pull autosyncs
**
**    on,open=off            Autosync for most commands, but not for "open"
**
**    off,commit=pullonly    Do not autosync, except do a pull before each
**                           "commit", presumably to avoid undesirable
**                           forks.
