Thanks for setting things straight :)

When I was looking into this I found man pages referencing shutdown(8)
in earlier releases but 4.2 was the first release complete with sources,
I assumed 4.1.snap was a post release / interim build.
Unfortunately, unlike the other directories, there is no file named TAPE
which describes the source, but anyway.

On CD1, in 4.1.snap/usr/doc/vmunix is changes.4-81 which contains "Bug
fixes and changes in 4.1bsd"

looking under

"Section 8 Major changes affecting system operations include"

appears

"shutdown
Is a new command which shuts the system down at a
specified  time.  It broadcasts messages to users
warning them as the downtime approaches,  records
the  reason  for  the  reboot  in a log file, and
cooperates with init in a cleanly shutdown  (e.g.
during  the  last  2 minutes of system operation,
users attempting to log in are told that the sys-
tem is going down and the reason for the shutdown
but not allowed to log in.)"
