I think that there also are other reasons why a real bourne shell 
won't run the scripts, and that, on solaris, having /usr/xpg4/bin
early in $PATH is needed.
 I'm sure the first /bin/sh I used applied IFS to the entire input
line, so after IFS=IFS you were in deep mire. So I've no idea what it
was like in the 1970's.
