We can simplify this logic and avoid spawning awk twice (which is relatively expensive in shell scripts) by performing the line counting, capping, and footer formatting in a single awk invocation. This also avoids potential Bash arithmetic syntax errors if awk output is unexpected.

max_lines=20
total_lines=$(awk 'END{print NR}' <<<"$markdownlint_output")
if (( total_lines > max_lines )); then
capped=$(awk -v max="$max_lines" 'NR<=max' <<<"$markdownlint_output")
capped+=$'\n…and '"$((total_lines - max_lines))"' more line(s) (capped at '"$max_lines"'; rerun markdownlint-cli2 manually for the full report)'
