SC2154 from strict bash mode example using trap

[taiki-e]

FYI, workaround is using trap -- '...'.

Thank you Taiki - that workaround is simpler, but I don't understand this well enough to suggest a wiki change for other people:

#!/bin/bash
set -uo pipefail
trap -- 's=$?; echo "$0: Error on line "$LINENO": $BASH_COMMAND"; exit $s' ERR
IFS=$'\n\t'

echo "Example of strict bash mode from Michael Daffin, see"
echo "https://olivergondza.github.io/2019/10/01/bash-strict-mode.html"

We can probably close this issue.
