In this case, a smarter regexp is enough:

  server_name ~ ^([^.]+\.)?([^.]+\.)?([^.]+\.)?([^.]+\.)?myserver\.net$;
  root /var/www/docs/myserver.net/$4/$3/$2/$1/public;

Add as many ([^.]+\.)? blocks as you need. This works because /var/www/docs/myserver.net/////public is a valid UNIX path, equivalent to /var/www/docs/myserver.net/public
