Hm.. I was trying to avoid a complicated script:
df -h | {
while read dev size used avail perc mount
do
        [ "${dev%%/dev/*}" ] && continue
        [ -z "$size" ] && read size used avail perc mount
        S="${#dev}"
        if [ $S -gt 23 ]; then
                T="\n\t\t\t"
        elif [ $S -gt 15 ]; then
                T="\t"
        elif [ $S -gt 7 ]; then
                T="\t\t"
        else
                T="\t\t\t"
        fi
        echo -e "$dev$T$size\t$used\t$avail\t$perc\t$mount"
done
}

What about:
df -h | sed -ne '/^\/dev\/[^ ]*$/N' -e '/^\/dev\//p'
