Pills for users with backticks get converted to code when complimented with another backtick

[turt2live]

Where curly brackets represent a pill, here's an example:

{Bob}: Hey

  "content": {
    "body": "TravisR`: hi there`",
    "msgtype": "m.text",
    "formatted_body": "[TravisR<code>](https://matrix.to/#/@travis:t2l.io): hi there</code>",
    "format": "org.matrix.custom.html"
  },

We (obviously) shouldn't be parsing the display name within the pill as markdown (though I fear that might be quite tricky to implement).

At the moment I can only think of display-names-containing-markdown that might make things look a bit cosmetically weird. If there's anything worse than that this might be worth bumping to a P1.

Another case:

The solution here would probably be to escape special characters in the URL text (using backslashes) and the hyperlink (using percent-encoding).

The current rendering itself does seem to be correct according to CommonMark: https://babelmark.github.io/?text=%5Bfoo%60%5D(http%3A%2F%2Fexample.com%2Fbar%60%2Fbaz) - so this would be an issue in the code that converts a highlight to a Markdown link, not in the client rendering.
