pacman_pending_updates outputs nothing if no updates

[solsTiCe d'Hiver]

The plugin at plugins/other/pacman_pending_updates is broken when no updates are available. It outputs nothing, and it seems the node is not responding.

checkupdates shows no output if there is no available updates but also returns 2 as return code.

This means the if blocks of the script is not run.
One need to change the code or take care of return code 2

Here is a patch of a possible fix:

Thank you for your suggestion!

I implemented an equivalent fix now.
