Enforce Markdown: Multiple headings with the same content

Rule MD024: We allow duplication for headings with different parents, but not within the same parent.

Nice, didn't know about this option.

Couldn't this cause issues in URL anchors though?

@sabiwara ExDoc at least deals with duplicate headers (and I'd expect most markdown renderers to deal with it too).

Note that what this rule is doing is avoiding the duplicated headers within a document; in particular within the same section.

Yes but the rationale for the rule seemed to be about anchors, hence my question.

Rationale: Some Markdown parsers generate anchors for headings based on the heading name; headings with the same content can cause problems with that.
