(author here) That's a very similar problem, but it looks like it's sloppy about escaping. Correct me if I'm wrong, but you could have a change description that looks like: Fix escaping of \*. And it wouldn't be printed correctly because it conflicts with Markdown's own escaping. $ echo 'Fix escaping of \*' |markdown <p>Fix escaping of *</p> Or: Fix parsing of a[i]() $ echo 'Fix parsing of a[i]()' | markdown <p>Fix parsing of a<a href="">i</a></p> In other words, you have a "markdown injection attack" (which is probably not very consequential, but it leads to bad output.). The whole point of this exercise is that the escaping is 100% correct.
