This information is redundant with the position information already provided. Also, no other -m diagnostics print out function name. While here, report parameter leak diagnostics against the parameter declaration position rather than the function, and use Warnl for "moved to heap" messages. Test cases updated programmatically by removing the first word from every "no match for" error emitted by run.go: go run run.go |& \ sed -E -n 's/^(.*):(.*): no match for `([^ ]* (.*))` in:$/\1!\2!\3!\4/p' | \ while IFS='!' read -r fn line before after; do before=$(echo "$before" | sed 's/[.[\*^$()+?{|]/\\&/g') after=$(echo "$after" | sed -E 's/(\&|\\)/\\&/g') fn=$(find . -name "${fn}" | head -1) sed -i -E -e "${line}s/\"${before}\"/\"${after}\"/" "${fn}" done Passes toolstash-check.
