Hi.
Let's see what we can do about cutting back a little on the verbosity,
and upping the utility...
-------------------------
#!/bin/bash
pkg=()
desc=()
count=-1
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
}
