Actually, I think this is due to the []-date test failing: #580825.

However, it is true that with the recent change in cron, checkarray
should not exit non-zero when there are no arrays, I guess.
I changed that to never exit non-zero, even if --cron is not given.
The warning is emitted if run without --cron, and that should be
enough.
