LaTeX: prevent auto-fill to break up equations

[Jonas]

Hi,


for formulae in the text I use $formula$. The formulae can be very
long but I don't want to have them on two seperate lines. How can I
prevent emacs to break the line if I am in th $$-"environment".

The best would be the following:

"Blablablabla $long_formula$"
is transformed into
"Blablablabla
$long_formula$"

Any idea?


Cheers
