Subject: Scnaf Patch?

It seems pos is undefined for STDIN.
In order to use scanf for console input I had to change the line 
       start_position = pos
in class IO, def scanf(str, &b) in lib/ruby/1.8/scanf.rb into
       if self == STDIN
	 start_position = 0 
       else
	 start_position = pos
       end

Any ideas?
