checkupdates: useful output for cron

checkupdates is great, but currently it is not very useful with cron.

Chris Down wrote checkupdates-cron:

checkupdates-cron is a tiny wrapper around the Arch Linux checkupdates script that will only print output if the updates available are different than the last time they were checked. This is useful if you run checkupdates as part of a cronjob, as it allows e-mails only to be sent when the available packages change, and not every time (which results in a lot of e-mails to sift through).

This is super useful.

I would love to see:

• pacman-contrib include checkupdates-cron

or

• checkupdates get a --cron option with this functionality.

What do you think?

Thanks, and keep up the good work!
