If the "old post" is the one he explains why he chose not to allow
fuzz by default, I think you got all what you need.  Basically, he
wanted you and his users to make sure that the patch they are having
trouble with applying can be due to only insignificant difference
and it is safe to apply with reduced context, instead of blindly
accepting a fuzzy patch application.
