As suspected, there was a loose nut between the seat and the keyboard.

The empty output of "echo $IFS" misled me into thinking that IFS was unset.

I see now that "echo" does not display the values of bash shell
variables.  One can grep the output of "set" to find them:

  bash$ echo $IFS
  bash$ set | grep IFS
  IFS=,

Thanks,
Chris
