  "break" keyword inside a while-condition doesn't work as expected : it breaks 
the wrong loop.

  # 1) should raise a parsing error  (but it doesn't)
  while break ; true ; do true ; done 

  # 2) should break the outer loop  (but it doesn't)
  while true ; do while break ; do whatever-because-never-reached ; done ; echo 
fail ; done

   I don't know.
