[pacman-dev] pacman sorting incompatible with 'sort' command

pacman internal sorting on package names differ from the one implemented in linux 'sort' command. pacman treats '-' (hyphen) differently. Testcase: 1. Install i3 group. It will install i3-wm, i3lock and i3status 2. Check the following commands: --($:~)-- pacman -Qeq | grep i3 i3-wm i3lock i3status --($:~)-- pacman -Qeq | grep i3 | sort i3lock i3status i3-wm --($:~)-- pacman -Qeq | grep i3 | sort -c sort: -:2: disorder: i3lock
