Doing
 C-x h [mark-whole-buffer]
 <tab> [indent-for-tab-command]
just makes indentation out of whack, here where we use shopt -s extglob
patterns. emacs-version "25.1.1".


#!/bin/sh
b=256 t=10000
shopt -s extglob
while read cid
do
    echo -n "$cid: "
    case $cid in
	+([0-9])-[0-9][0-9])
			    printf "%d\n" $((${cid%-*} * 256 + ${cid#*-}))
			    for i in 01 11 21 31 41 51
			    do printf "%d %s\n" $((${cid%-*} * 256 + i)) $i
			    done
			    ;;
			    +([0-9]))
				     printf "%06d-%02d\n" $((cid / b)) $((cid % b))
