  Bug#35224: mysqldump --help is very confusing
  
  The presence of "--skip" parameters is obscure, when it should be
  obvious from the text.
  
  Now, for boolean options, when they're default to ON and the --skip
  is more useful parameter, then tell the user of its existence.

    Remove message about defaultness, as that's encoded in the other 
    values and will now be extracted.

    For printing options, if the option is boolean and defauts to ON,
    then tell the user so, and tell them of the --skip option.
