should man pages mention exit values even if run of the mill?

[Dan Jacobson <jidanni@jidanni.org>]

Should man pages mention exit codes, even if standard? There perhaps
should be a policy statement on this.
I'm the old fashioned type who likes to see them mentioned no matter
what. Let's one know the programmer even remembered to set them.

And even more important is saying the definition of success. E.g.,
0: connection is guaranteed to now be terminated
0: signal sent, connection usually terminates soon
1: unable to even send signal
1: unable to send signal or sent signal but unable to terminate connection
