JS to "fixup" ASCII art on old Apple docs, e.g https://support.apple.com/kb/TA40730

fixer.js

document.querySelector('.SUMMARY').childNodes.forEach(function(e) { 
  if (e.nodeType == Node.TEXT_NODE && (e.textContent.match(/[+|-]/g) || []).length > 2) { 
    var n = document.createElement('code'); 
    n.textContent = e.textContent.replace(/^[\r\n]*(.*)[\r\n]*$/, '$1'); 
    n.style = 'white-space:pre-wrap'; 
    e.parentNode.replaceChild(n, e); 
  } 
});
