I believe this broke some time after 1.6.8, when pos was removed from
STDIN.  It was subsequently fixed, though:

  wobblini:~$ ruby -vrscanf -e 'p STDIN.scanf("%d%s")'
  ruby 1.8.2 (2004-07-29) [i686-linux]
  123 abc
  ^D
  [123, "abc"]

(The line you quoted is now:

   start_position = pos rescue 0

:-)
