[net.unix] #! in 4 bsd

The #! feature was added to the Berkeley Unix system in 4.1; it was not
present in 4.0.  The major motivation, I believe, was to allow Pascal
interpreter files to be execed directly without using the disgusting
hack of putting an executable interpreter front end on them.  In fact,
this is a nice general solution to the problem of running files which
are interpreted by some other program.  Cshell scripts are just a special
case of that.
