From tgr on wikitech-l:

| Another low-hanging fruit would be to special-case the situation when
| editor A adds text to the end of a section but does not start a new
| section, while editor B adds a new section to the same place. This is
| currently a conflict as they both try to insert to the same "slot" between
| paragraphs, so a generic merge tool cannot figure out whether those
| additions conflict and what would be the right order if they don't;
| however, knowing the semantics of wikitext, inserting the text from A first
| and the one from B after that seems a pretty safe bet. This kind of
| conflict is very typical on talk pages where people almost always edit the
| end of a section, and the few "hot topic" sections get the majority of the
| edits.

Seems sensible.
