(1) Change the syntax plugin handle() function to allow it to return false when there is no need to create a plugin render instruction for that particular match. Potentially this could impact plugins which return false as real data. If false is a problem value, null is a possible alternative.
This is primarily an efficiency change. It removes unnecessary rendering instructions from the instruction list.
I will be using it to shift handling of DOKU_LEXER_UNMATCHED matches from my plugins to the standard cdata handler. 

e.g.

    function handle($match, $state, $pos, &$handler){
        switch ($state) {

        ...

          case DOKU_LEXER_UNMATCHED :
            $handler->_addCall('cdata',array($match), $pos);
            return false;

        ...

(2) Add an optional third parameter, $new, to the plugin_load() function.
@param $new bool true to return a new instance of the plugin, false to use an already loaded instance 
function &plugin_load($type,$name,$new=false)

- Chris





Just to get this straight:  these changes have no effect unless we are
   (1) checking for a false return value from handle()
Or
(2) loading a new instance of a plugin from our own plugin code

The latter might affect the plugin tool of DokuWikiFCK.  I'd have to check.
