Hi Nicolas,

I think there are also some relevant points which I haven’t mentioned so far,
separate from my thoughts that since we’re using the LaTeX syntax we should be
consistent with how LaTeX treats this.

I think we already do special-case $...$' somewhat. When refer to inline
elements like bold, verbatim, italic, etc. they sit in the text. Semantically,
this doesn’t hold for $...$' either. The semantically inline maths element is
$$...$$'. Considering other “inline” syntax elements, like bold, verbatim,
italic, etc. if you spread the delimiters across multiple lines that doesn’t
work. So I’d argue the ship has already sailed on treating $...$' differently
to other inline elements.

If you’re wondering why I’m so opposed to the current behaviour, that is probably
best explained by a more realistic demo that what I have in the commit message.

Suffice to say, I find the second terrible to read compared to the first.
Furthermore, when using org-latex-preview, wrapped $...$' blocks join lines,
resulting in lines that are displayed going off edge of the page after filling.

Basically, this leads to a worse experience when using Org in what I would think
to be a perfectly reasonably way.

All the best,
Timothy
