Title: tar "t" option
Article-I.D.: stolaf.887

Ah, yes, the missing code for the "t" option of tar(1).  We are running
V7, and this past summer on of my fellow workers complained about
the "t" option not working.  I went in, found out that the code didn't
exist, so I wrote the stuff.  It's not that much to add, my fixes follow.
We have been running for months and no one has complained.
