Dear Cecil,
I would be glad to fix the script, but may I only ask for some simple
explanation of what your code does? (I hardly know bash.)

To make the shell script setuptex more robust I would add at the beginning:
set -o errexit
set -o nounset
function isVarSet() {
if [[ ${#} -ne 1 ]] ; then
fatal "${FUNCNAME} "
return
fi
declare -p ${1} &>/dev/null
return
}
And use:
if ! isVarSet PS1 ; then
instead of:
i
