Don't forget to goad translators into causing more trouble by adding a custom string for the --downloadonly status message

When downloading packages only with pacman -Syuw my shell outputs "Starting full system upgrade...". What I would like to be displayed instead if the --downloadonly flag is set is something like "Downloading package updates..."
