Jeremie Le Hen 94582faa19 Include the calling context in the mail subject, if any.
More concretely, periodic security scripts defaults to being
called from daily ones -- daily context -- so the mail subject
will now be "${HOST} daily security run output" instead of
"{HOST} security run output".

If you switch the period of some security checks to weekly, you
will receive another email "${HOST} weekly security run output".
