Synopsis:
   on [<modes>]action [<serial#>] [-|^]<match> { <action> }

Description:
   This hook is triggered whenever the client observes a CTCP ACTION.  It
   will hook when the recipient is either the user or a channel.

Parameters:
   $0    nickname of the ACTION sender
   $1    target of the ACTION (user's nickname or a channel)
   $2-   message body of the ACTION

Examples:
   To distinguish personal actions from those sent to a channel:
      on ^action "*" {
         switch ( $1 ) {
            ( $N ) { echo *> $0 $2- }
            ( $C ) { echo * $0 $2- }
            ( * )  { echo * $0/$1 $2- }
         }
      }
