Command: vacation

  Format: vacation { mm/dd/yy | none }

Sets a "vacation" marker on your subscription to the selected list,
indicating you don't want to receive submissions to the list until the
specified date.  Specifying today's date, any earlier date, or the word
"none" clears this setting, and you will receive submissions.

The fact that a subscriber is on vacation does not appear in the output of
"members", but is visible under "showmember".
