I don't see any "&ndash;" in that article, but whatever happened to structured text markup, like <kbd>, <samp>, <var> and <code> ? Even the simplest examples like 'cd -' are inline-styled like "<span id="crayon-5979e5b4c1d14672735590" class="crayon-syntax crayon-syntax-inline crayon-theme-xcode crayon-theme-xcode-inline crayon-font-monaco" style="font-size: 18px !important; line-height: 18px !important;font-size: 18px !important;"><span class="crayon-pre crayon-code" style="font-size: 18px !important; line-height: 18px !important;font-size: 18px !important; -moz-tab-size:4; -o-tab-size:4; -webkit-tab-size:4; tab-size:4;"><span class="crayon-i">cd</span><span class="crayon-h"> </span>–</span></span>"
