Using the new version:

  $ ./ruby -v
  ruby 1.8.0 (2003-10-06) [i686-linux]
  $ ./ruby -e 'p ["a"].inject("start") {|x,y| "b"}'
  "b"
  $ ./ruby -e 'p ["a"].inject("start") {|x,y| break "b"}'
  "start"

I'm still not understanding why these should be different, or how
"start" gets into the first one (the first block) at all.
