Snip....

Been messing around with this a little, added pacman -Qs option, single 
space option (-d default) and some colours. Wrapped it in a function so 
can call it pacside [-qs] schstring.
Thought I'd put it back up in case anyone's interested.

pacside() {

    sidesch() {

        bldblu='\e[1;34m' # Blue
        bldwht='\e[1;37m' # White
        txtrst='\e[0m'    # Text Reset

        pkg=()
        desc=()
        count=-1
        WIDTH=${WIDTH:-70}

        while read line; do
            if [[ $line =~ 
^(testing|core|extra|community|community-testing|local)/* ]]; then
                (( count++ ))
                line="$(echo $line | echo $line |cut -d "[" -f1 )"
                pkg[$count]="$line"
              continue
            fi

            desc[$count]+="$line"
        done

        i=0
        while (( i <= $count )); do
            IFS=$'\n' read -r -d'\0' -a blockdesc < <(fmt -w$WIDTH <<< 
"${desc[i]}")

            paste -d' ' <(printf "${bldblu}\t%-60s" "${pkg[i]}") <(echo 
-e "${bldwht}${blockdesc[0]}${txtrst}")

            for line in "${blockdesc[@]:1}"; do
            printf "${bldwht}\t%-61s%s\n" "" "$line"
            done

        (( ++i ))
        [[ $1 != -s ]] && echo
        done
        }

    [[ -z $2 ]] && pacman -Ss $1 | sidesch
    [[ $1 == -s ]] && pacman -Ss $2 | sidesch -s
    [[ $1 == -q ]] && pacman -Qs $2 | sidesch
    [[ $1 == -sq ]] || [[ $1 == -qs ]] && pacman -Qs $2 | sidesch -s
}
