Removal of '[' and ']' from char blacklist of vfs:real module

* After about three months of use, Guzle has reported back no problems with these characters being removed from the blacklist of this module
* As noted in the forum thread, these characters should not be removed from the 'Virtual' module, only the 'Real' module.
