new policy topic: cron jobs (sec 3.5)

["Adam P. Harris" <apharris@onshore.com>]

I would like to make it policy that cron jobs do not emit any message 
during normal processing.  Here's a possible wording:

    Any cron job which is installed should not emit any messages to 
    STDOUT or STDERR during normal processing.  Messages should
    only be emitted if an unexpected condition occurs during execution.
    Cron jobs are allowed to log messages to a log file, i.e., use 
    syslog() under any conditions deemed appropriate by the maintainer.

RATIONALE:

Ever night I get the following email, and it is very annoying.
