Revision: 9115
http://supercollider.svn.sourceforge.net/supercollider/?rev=9115&view=rev
Author: bbozkurt

Log Message:
-----------
cleaning dangling b.numFrames codes of pvc* fft help files after migration to LocalBuf constructs in fft code, the current examples were broken. They were probably left unnoticed because in most cases some of those help files defined the variable b as a buffer here or there within the session...
