[PATCH] RecursiveTreeIterator implementation

Hi, I have seen a "NEEDS DEVELOPER" flag on the TODO for the "Implement RecursiveTreeIterator in C" task, so I would like to propose my implementation [1]. Currently it follows the PHP implementation, except that it does not have a $prefix public property (how about a private property and a setter method ?). I hope this patch will be useful. Please say me if anything is wrong with it. [1] http://arnaud.lb.s3.amazonaws.com/RecursiveTreeIterator.patch [2] http://arnaud.lb.s3.amazonaws.com/RecursiveTreeIterator-phpt.tar.bz2 Regards, Arnaud
