Re: [AUCTeX] 11.88.9 and fill-paragraph oddness

[gojjoe]

Hi George,

You can change this behaviour by customizing the variable
Latex-fill-break-at-separators

I think it should work if you check "Opening Display Math 
Switch" and "Closing Display Math Switch" and leave the 
other options unchecked, in the customization menu for that 
variable.

This change has been made because '$...$' and '\(...\)' were 
behaving inconsistently with respect to paragraph-filling.

Developers: maybe it'd be good to change the default value 
of "Latex-fill-break-at-separators" then?

Cheers,
J
