bug#21645: Inquiry: reproducibility of a paragraph-fill bug

[gojjoe]

Hi Adrian,

> Please revert!

You can revert to the original behaviour by customizing the 
variable 'Latex-fill-break-at-separators', checking "Opening 
Display Math Switch" and "Closing Display Math Switch" and 
leaving the other options unchecked.

I think the developers are planning to setting this variable 
that way by default, so the original behaviour (with respect 
to $...$, but now also with respect to \(...\), more 
consistently) will be restored.

Cheers,
J
