When commenting with the pipe character ('|'), it gets 'escaped' with a backslash.

Add a comment to any line of code in a pull request.

Use a pipe character in regular text (not in a code snippet).

Save the comment.

Pipe is preceded by a backslash in the resulting comment.

Even upon re-editing the comment, the backslash is retained, and will be re-added.
