Very likely, since you left it behind at Caltech as well; it was
in sh on cithep (a hostname meaningless to many but rob will remember)
when I arrived in 1980.

It was in the version of p you left behind there as well.

I can confirm that spname remained in the shell through V10
(it's still in my copy), but it seems to have disappeared from p.
