Steve indubiately did not start from mine, although there was a great
deal of interaction, joint evolution, discussion, etc.  If you look it up,
it says it took features from the original UNIX shell & from the PWB/UNIX
shell, and thanks DMR & I for many discussions [Ken was off at UCB while
much of this was going on.] I doubt that any actual code from the PWB
shell was in Steve's.
