New Revision: 222697
URL: http://svn.freebsd.org/changeset/base/222697

Log:
  find: Exit if there is an unknown option.
  
  Ignoring the parameter with the unknown options is unlikely to be what was
  intended.
  
  Example:
    find -n .
  
  Note that things like
    find -n
  already caused an exit, equivalent to "find" by itself.
