!op
###  match +<attr> [[start] limit]
   shows you user records which have the attributes listed (such as
   '.match +of' to show all users who are friends and ops)
###  match <wildcard-string> [[start] limit]
   shows you user records where the nickname or any of the hostmasks
   match the wildcard string shown.

   the default limit is 20, meaning that if more than 20 user records
   match your requirements, only the first 20 will be shown.  you can
   change this limit by specifying one on the command line, though.
   if you include a limit, you may also include a starting place (the
   default is 1).  for example, to list the first 15 users who have
   hostmasks from clemson.edu:
      .match *clemson.edu 15
   to get the next 10 (if there are more than 15), you ask to list
   numbers 16 thru 25:
      .match *clemson.edu 16 25
