I haven't checked this recently, but I thought another incompatibility
was that deeply nested loops in Bourne shell were forked as new
processes.  This means that variable assignments in these inner loops
are not exported outside these deep loops.  Korn shell fixed up this mess.

I think I stumbled on this in our old V7 Unix.
