POSIX compliant cron example

Browse Source 
Changed the cron auto example to be POSIX compliant and use full paths.
Changed `exit` variable to `RC` (commonly used in system scripts for "return code") as `exit` is a shell builtin.
Added note about setting the full path as $PATH may not be set.

The path to `acme-client` should be modified to suit your system. The full path should be used as the system path may not be set up in your cron environment.
