=>/<= converted into ≥/≤

Great script, I really love it that I do not have to install 100+MB pandoc to convert some basic Markdown to HTML. Thank you for the script!

I think I found a bug:

$> printf "\`\`\`\narrow function => return\n\`\`\`" | ./md-to-html.sed
<pre><code>arrow function &amp;ge; return
</code></pre>

The script converts my "=>" into ≥. I think this is not necessary and lines 9, 10, 19 and 20 can safely be removed, correct?
