The wiki markup parser is very confused about the title of Line-comment in XML — one other than <!— .. -->.
- The title ends in
<!, so the last part gets stripped in some contexts.
- Some pairs of dashes (which are integral to the meaning of the question) are converted to an mdash, but others aren't. (They also seem to be converted on the fly, as I've seen the page render with two dashes and then switch to long dashes.)
But you can't simply wrap the part in backticks, because unlike wiki markup in the question itself, backtick code escaping doesn't work in the title.
How can I edit the title to be consistent and understandable?
