[lug] crontab range

[Davide Del Vento]

'right, I knew that and I forgot, silly me :-)
So I can go down from 4 to 3, possibly two lines, which is good progress.
Any idea to go down to one (without making the command dependent on time,
which is too cumbersome because it's already a wrapper of a wrapper that
gets used for different things at different times, so I can't change it and
I don't want to add another layer of wrapping)?
